3.18 CC/CV Priority

IT6500C Series is innovatively designed with CV/CC priority concept in the industry to solve various strict problems in long-term test applications and to make applications (e.g., speedy or no-overshoot operation of power supply) more flexible. As everyone knows, power supply has two working modes including constant voltage and constant c urrent, which correspond to two inside loops (CV control loop and CC control loop). Traditional power supplies always take CV loop as priority, which are not suitable for circumstances having high requirements on current overshoot. With new CC/CV priority concept in IT6500C, the user can realize CC control loop, response speed of CV control loop and any combination setting of control loops under CC and CV mode through the power supply menu interface to meet diversified field applications. With this function, the user can save a lot of costs as no purchased parts are required.

Example of application circumstance in typical configuration application:  Strict requi r ements on current overshoot

Set Priority as CC, CC-Loop as High and CV-Loop as Low. This priority is applicable for circumstances having high current overshoot requirements, like LED lamp, laser test, etc.

Tr aditi onal power supply has low priori ty due to sl ow CC loop spee d and ca nn ot quickly detect and inhibit current overshoot when the current reaches the set current. Through IT6500C menu, you can set the CC control loop to High priority to quickly make the power supply in constant current status so as to inh ibit current overshoot at the starting moment. Waveform characteristic s are as shown below. Yellow means outp ut voltage and green means output current.

Function and Features

 Start up the over-current range of surge current to quickly set up voltage. As the input end of p ow er sup pl y modul e has l ar ge capa city, large sur ge c urr ent

will generate at starting moment, which will lower the power supply v oltage at the input si de of DC mod ul e. I n addi ti on, thi s wi ll resul t in CC curr ent l i mit mode, where low supply voltage will cause under-voltage protection of DC module, making startup fails.

Set Priorit y as CV, CC-Loop as Low and CV-Loop as High. The voltage is not sensitive to current at phase step and voltage edge can be realized quickly. In addition, this avoids surge current at startup, which may cause CC mode and startup failure. Waveform characteristics are as shown below. Yellow means output volt age and green mea ns output curr ent .

 Battery charge-discharge, high spee d, seamless, and no overshoot Set Priority a s CC, CC-Loop as High and CV-Loop as High to represent CC

characteristics entirely. In this way, you can quickly create current and inhibit current overshoot so as to realize seamless and no-overshoot current switch.

Function and Features

Waveform characteristics are as shown below. Yellow means output voltage and green means output current.

When CV mode is selected from CC/ CV P r ior ity, the load current value set in List wave file fails and discharge cur r ent is the I-set value se t in the power supply Setup menu. Pay att ention to current value to avoid over-current. For detailed ch ecking and se tting methods, refer to 3.14 Load Function.

To set loop and CC/CV m ode, follow the method below.

1. Press the composite key [Shift]+[P-set] (Menu) to enter the Configuring Menu.

2. Select “CONFIG” in t he men u and press [Enter] for confirmation.

3. Select “Loop-Mode” w ith Right key and press [Enter] for confi rmation.

4. Select CV-Loop or CC-Loop to set the loop response spee d.

5. Select Priority and set the current priority work mode, which defaults to CV mode.

3.19 LIST Operation

3.20 PV Simulation

The PV array/module/cell is a device that converts from light energy to electric energy. It is made by a simple semiconductor PN junction that the major output characteristic is that there’s only one maximum power point (MPP) at certain sunlight intensity. The PV inverter is designed to track this point to harvest maximum energy that is generated by the PV array. Therefore, all the PV inverters have the maximum power point tracking (MPPT) mechanism built-in, and it is very important to test the efficiency of this MPPT.

Load dump dynamic behavior

This test is a simulation of load dump transient occurring in the event of a discharged battery being disconnected while the alternator is generating charging current with other loads remaining on the alternator circuit at this moment.

 The amplitude of load dump is determined by the rotational speed of

alternator and the strength of magnetic field in the case of disconnection of the battery.

 The pulse duration of load dump is mainly determ ined by the time constant

and pulse a mplitude of the excitation circuit.

Inside most novel alternator, the amplitude of load dump is decreased by increasi ng the limiter diode (clamping di ode) . The load dump may be caused by cable corrosion, poor cable contact or disconnecting the battery intentionly when the engine is running.

The pulse shape and parameters for an alternator without centralized load dump suppression are given in follow.

E-09 Reset Behavior

The reset behavior of a component in its environment is simulated and tested. Test boundary conditions (e.g. assembly, terminal, system) must be described in detail. During operation, an arbitrary sequence of repeated switching-on/off procedures occurs; this must not lead to an undefined behavior of the component. The reset behavior i s represented by a volt age variance and a time variance. Two different test sequences are required to simulate different switch-of f times. A compo nent must al ways undergo both sequences.

Function and Features

E-11 Start Pulses

When starting the engine, the battery voltage drops to a low value for a short period and then slightly rises again. Most components are activated directly before start ing for a short period, then deactivated during starting and activated again after star ti ng when t he engi ne i s runni ng. Thi s test serves t o verify normal operation under these conditions. The starting process may be performed under different vehicle starting condit ions, cold start and warm start. In order to cover both cases, tw o different test sequences are required. A co m ponent must always undergo both sequences.
