3 PRODUCT CHARACTERISTICS
A brief theoretical explanation about the operation and a simplified electrical scheme of the power cells and their connections are presented below. The basic operation of the control system is presented at the end of this chapte r.
The MVW3000 is a frequency inverter designed to control medium voltage motors at the rated values of 2.3 kV to
13.8 kV and for a power range of 150 HP to 5400 HP. Based on a topology where the low voltage cells (< 1000 V) are connected in series to form each inverter phase, its assembly is modular, enabling different configurations if necessary to drive high power motors.
NOTE!
The characteristics contained in this manual were based on models of the standard MVW3000 intended for applications on 6.6 kV motors. Therefore, the MVW3000 used in the general illustrations will contain 18 low voltage power cells (six in series per phase). Notice that the MVW3000 can be engineered to meet the needs and technical specifications of our customers. Contact out technical team for more details.
3.1 INPUT TRANSFORMER
The MVW3000 inverter has an input transformer, because the cascade cell topology demands the feeding of each cell to be insulated from each other. This transformer is built so as to meet the different functions for the MVW3000, such as the necessary insulation for the power cells, cancellation of the harmonic current coming from the cell input rectifiers, and it also has an auxiliary winding responsible for the system pre-charge.

Product Characteristics
The transformer configuration is made in star – extended delta, with phase-shifting angles j° between the secondary windings of one same phase. The main primary windings (star connection) and the auxiliary input windings (also star) do not present phase shifting between each other.
The transformer is designed according to the number of cells used on the inverter. 3x3xn windings (number of motor phases x number of cell input phases x number of cells per phase) form n isolated secondary windings that process 1/(3n) of the converter rated power, totalizing one secondary winding per cell.
Motor Voltage [kV] 2.3 3.3 4 .16 5.5 6-69 7. 2 8
Secondary Windings 3x2=6 3x3=9 3x4=12 3x 5 =15 3x 6 =18 3x7= 21 3x8=24
The transformer secondary windings have phase-shifting designed according to the number of cells and the specified harmonic level, and it may be engineered upon the customer’s request The phase-shifting help cancel the harmonic components coming from the non-controlled semiconductors devices. As each cell has a 6-pulse diode rectifier at the input, and the secondary windings have a phase-shifting between each other, the transformer primary winding perceives multiples of six pulses in its windings.
The bigger the number of pulses, the smaller the phase-shifting angle between the secondary windings, and the smaller the Harmonic distortion rate observed by the transformer primary winding. Smaller phase-shifting angles imply more complex manufacture and parameter control of the transformer. Thus, a good complexity­performance ratio is sought.
For the 18-cell MVW3000, the 36-pulse transformer Figure 3.2 on page 3-3 is used, which offers good cost effectiveness with great performance regarding harmonic component cancellation and reduced cost, in comparison to transformers with more pulses.
Table 3.1 on page 3-2 contains the possible input transformer configurations for different numbers of cells
installed on the MVW3000 panel.

3.2 POWER CELLS
The power cells used on the arms of the MVW3000 are single-phase low voltage inverters (output voltage of 690 V
rms
), in a topology known as H bridge or full bridge. A basic diagram of the rms power cell circuit can be seen in Figure 3.4 on page 3-4. Each cell has the feeding of one own secondary winding (three-phase) of the main transformer, which ensures the converter medium voltage insulation.
The three-phase voltages of the input of the modules are then rectified by a Graetz bridge using non-controlled semiconductor devices (diodes), forming one own DC link (direct current) with the addition of the capacitors to the cell (represented by symbol C1). They can be electrolytic or plastic film capacitors, depending on the model of the used cell.

Figure 3.4: Basic diagram of a power cell
IGBT (Insulated Bipolar Gate Transistor) controlled semiconductor devices are used to implant the inverter bridge in H; thus, each power cell has four IGBTs in the configuration shown above. During operation, the voltage between FA and NE output terminals has three possible voltage levels. Considering that the DC link voltage of each cell is VDC and that only two IGBTs can be operating simultaneously (due to short circuit protection), when S1f and S2n are operating, the voltage between FA and NE will be + VDC, whereas if S1n and S2f start operating, the voltage between FA and NE will be –VDC. If S1n and S1f or S2n and S2f are turned on, the voltage, in both cases, will be equal the zero.
To protect the modules, two fuses F1 and F2 are connected to the input phases R and T, as shown in Figure 3.1
on page 3-1. In case a module presents some fault, the bypass system, when available, will be responsible for
circumventing the fault, removing it from the series and enabling the operation to continue.
When that occurs, control strategies will be applied so that the load remains operating. Further information can be found in Chapter 8 SPECIAL FUNCTIONS on page 8-1, in Section 8.3 CELL BYPASS on page 8-5.
Each power cell has one local control module. This module communicates with the main control module by means of an optical-fiber interface, necessary to obtain, in addition to the insulation degree required for the communication, noise immunity, greater robustness and reliability, characteristics necessary for the application. The local control makes acquisitions and monitors relevant magnitudes for the cell operation.
Some of the monitored magnitudes are the line voltages of the power cell, temperature of the diode modules and IGBTs, voltage of the DC link capacitors, voltage of the cell power supplies, among others.
The local control is also responsible for local activations, such as the switching of the IGBTs and the trigger of the bypass system. In case the cell presents readings out of the expected operation standards, for example, temperatures close to damaging the semiconductors, overvoltage on the DC link, or other faults predicted by the control, the bypass system may be activated for protection against a possible cell failure or for removing an already damaged cell from operation.

3.3 CONNECTION OF THE CELLS
To form a three-phase output, a number “n” of power cells that operate with 690 “V
rms
” of output are rms grouped in series per phase. The cell sets that represent phases U, V and W are connected in star configuration, with a floating neutral in common with the phases, as indicated in Figure 3.5 on page 3-5.

Figure 3.5: Cell-to-phase connection diagram
Figure 3.6 on page 3-6 shows the transformer, input switchgear and secondary winding connected to each
cell. This association in series enables more voltage levels at the inverter output. Locally, each cell produces three voltage levels; however, at the converter three-phase output, it is possible to obtain 2n + 1 levels on the phase voltage and 4n+1 levels on the line voltage.
This effect occurs, because the voltage of each phase is instantaneously given by the addition of the voltages at terminals FA and NE of each cell pertaining to the analyzed phase. Figure 3.7 on page 3-7 shows the sum of the voltages of each cell to form the phase voltage in a 9-cell MVW3000 (3 per phase).

Therefore, increasing the number of cells per phase, in addition to enabling the drive of motors with higher voltages and powers, a better sinusoidal shaped wave is obtained. Thus, the converter provides a smaller THD (total harmonic distortion), reduction of noises and vibration on the motor, operating with high efficiency.

Product Characteristics
3.4 CONTROL
The MVW3000 has protections against overload, short circuit, current limit, under and overvoltage, overtemperature, ground fault and monitoring of the individual faults of each power cell. The control type can be selected by the user between: scalar control (constant V/f ratio) or vector control (sensorless or with feedback by speed sensor).
The MVW3000 inverter uses the PWM modulation technique (Pulse Width Modulation); from the direct voltage of each independent DC links, it synthesizes an alternate voltage with variable frequency and amplitude at the output terminals. The medium voltage level is obtained at the converter output terminals from the association of “n” low voltage cells in series. For further information on the central control, refer to Section 4.3 CONTROL RACK
on page 4-6.

Figure 3.8: Central control simplified diagram
The output currents of the three phases (motor currents) are measured using the Hall-effect CTs (current transformers). Those current signals are sent to the central control board. The measurement is done for indication on the HMI and for implanting the converter control and protection functions.
The pre-charge is done by means of an auxiliary winding of the input transformer, which is driven by the inverter auxiliary supply circuit via current limiter elements. In order to prevent high starting current levels on the inverter, activation of protection systems or even damages to its own components, the cell capacitor pre-charge must be done through and auxiliary winding of the input transformer. The auxiliary supply is also responsible for feeding the control circuit and fans for the panel cooling.

4 TECHNICAL DATA
This chapter contains technical information on the MVW3000, cabinet details, input transformer, power cell and control rack. It also provides information about the available output filters for the MVW3000.
4.1 MVW3000 PANEL
The MVW3000 is assembled as coupled panels forming four distinct compartments. In the first column of the panel, to the left, are the input safety devices, such as fuses and the input circuit breaker/contactor (if installed). This part also shows the input transformer temperature on the temperature display. Below the safety devices, in a separate section, is the main medium voltage input transformer. In the central section, the inverter power cells are installed; each of the three columns shown in Figure 4.2 on page 4-2 represents each of the three inverter phases: U, V and W.

The handles of average tension that feed the cells of the invertor come from the secondary ones of the transforming one of entrance. The number of cables and conductor diameter varies according to the number and current of the cells installed on the MVW3000.
Each cell receives the input supply from and independent secondary winding insulated from the main transformer. In the right panel, in the upper compartment, is the control compartment, containing the main control, user interface, HMI, command and signalling, which are exclusively supplied by low voltage circuits.
The converter three-phase medium voltage output is located in the compartment below the control, and this compartment can also be used to install optional output filters.
The standard panels of the models equipped with drive system and input protection feature medium voltage fuses in order to protect the system against short circuit. The fuses must match the rated voltage of the input medium voltage circuit.
Table 4.1 on page 4-2 presents the fuse models recommended for the standard inverters where the input and
output voltage are the same; for applications with voltage values different between input and output, the fuse model will be informed upon request.

4.1.1 Panel Constructive Aspects
The panel is made with steel sheets painted and processed (cutting, holes, folding, chemical treatment, painting and finishing) by WEG, ensuring the quality in all the levels of the manufacture process. The inverter parts that are not painted are zinc plated or have another suitable treatment in order to assure their resistance against corrosion.

The MVW3000 panel is supplied, in its standard structure, with degree of protection IP41 (openings smaller than 10 mm and protected against ingress of vertical drops). They can be supplied with distinct degrees of protection according to the customer’s needs.
The panel cooling is done by means of forced convection. The air enters through the opening on the panel front doors, goes through the transformer windings and also the power heatsinks located in each power cell. The hot air leaves through the top do painel, of the panel, where the exhaust fans are located, allowing maintenance without the need to open the inverter doors.
