Recommended Interface Circuitry for the Primary Side Connector

Fig. 5 Recommended user interface of 2SC0435T (primary side)

Both ground pins must be connected together with low parasitic inductance. A common ground plane or wide
tracks are strongly recommended. The connecting distance between ground pins must be kept at a minimum.

Description of Primary Side Interface

General

The primary side interface of the driver 2SC0435T is very simple and easy to use.

The driver primary side is equipped with a 10-pin interface connector with the following terminals:

 2 x power-supply terminals
 2 x drive signal inputs
 2 x status outputs (fault returns)
 1 x mode selection input (half-bridge mode / direct mode)
 1 x input to set the blocking time

All inputs and outputs are ESD-protected. Moreover, all digital inputs have Schmitt-trigger characteristics.

VCC terminal

The driver has one VCC terminal on the interface connector to supply the primary side electronics with 15V.

www.power.com/igbt-driver Page 8

SCALE™-2+ 2SC0435T

Preliminary Description & Application Manual

VDC terminal

The driver has one VDC terminal on the interface connector to supply the DC-DC converters for the secondary
sides.

VDC should be supplied with 15V. It is recommended to connect the VCC and VDC terminals to a common 15V
power supply. In this case the driver limits the inrush current at startup and no external current limitation of
the voltage source for VDC is needed.

MOD (mode selection)

The MOD input allows the operating mode to be selected with a resistor connected to GND.

Direct mode

If the MOD input is connected to GND, direct mode is selected. In this mode, there is no interdependence
between the two channels. Input INA directly influences channel 1 while INB influences channel 2. High level
at an input (INA or INB) always results in turn-on of the corresponding IGBT. In a half-bridge topology, this
mode should be selected only when the dead times are generated by the control circuitry so that each IGBT
receives its own drive signal.

Caution: Synchronous or overlapping timing of both switches of a half-bridge basically shorts the DC-link.

Half-bridge mode

If the MOD input is connected to GND with a resistor 72k<Rm<181k, half-bridge mode is selected. In this
mode, the inputs INA and INB have the following functions: INA is the drive signal input while INB acts as the
enable input (Fig. 6). It is recommended to place a capacitor Cm=22nF in parallel to Rm in order to reduce the
deviation between the dead times at the rising and falling edges of INA respectively.

When input INB is low level, both channels are blocked. If it goes high, both channels are enabled and follow
the signal on the input INA. At the transition of INA from low to high, channel 2 turns off immediately and
channel 1 turns on after a dead time Td.

Preliminary Description & Application Manual

The value of the dead time Td is determined by the value of the resistor Rm according to the following formula
(typical value):

with 0.6μs<Td<4.1μs and 72kΩ<Rm<181kΩ

Note that the dead time may vary from sample to sample. A tolerance of approximately ±20% may be
expected. If higher timing precisions are required, Power Integrations recommends using the direct mode and
generating the dead time externally (refer to the Application Note AN-1101 /4/).

INA, INB (channel drive inputs, e.g. PWM)

INA and INB are basically drive inputs, but their function depends on the MOD input (see above). They safely
recognize signals in the whole logic-level range between 3.3V and 15V. Both input terminals feature Schmitt­trigger characteristics (refer to the driver data sheet /3/). An input transition is triggered at any edge of an
incoming signal at INA or INB.

SO1, SO2 (status outputs)

The outputs SOx have open-drain transistors. When no fault condition is detected, the outputs have high
impedance. An internal current source of 500μA pulls the SOx outputs to a voltage of about 4V when leaved
open. When a fault condition (primary side supply undervoltage, secondary side supply undervoltage, IGBT
short-circuit or overcurrent) is detected, the corresponding status output SOx goes to low (connected to GND).

The diodes D1 and D2 must be Schottky diodes and must only be used when using 3.3V logic. For 5V…15V
logic, they can be omitted.

The maximum SOx current in a fault condition must not exceed the value specified in the driver data sheet
/3/.

Both SOx outputs can be connected together to provide a common fault signal (e.g. for one phase). However,
it is recommended to evaluate the status signals individually to allow fast and precise fault diagnosis.

How the status information is processed

a) A fault on the secondary side (detection of short-circuit of IGBT module or supply undervoltage) is

transmitted to the corresponding SOx output immediately. The SOx output is automatically reset
(returning to a high impedance state) after a blocking time Tb has elapsed (refer to “TB (input for
adjusting the blocking time Tb)” for timing information).

b) A supply undervoltage on the primary side is indicated to both SOx outputs at the same time. Both SOx

outputs are automatically reset (returning to a high impedance state) when the undervoltage on the
primary side disappears.

TB (input for adjusting the blocking time Tb)

The terminal TB allows the blocking time to be set by connecting a resistor Rb to GND (Fig. 5). The following
equation calculates the value of Rb connected between pins TB and GND in order to program the desired
blocking time Tb (typical value):

with 20ms<Tb<130ms and 71kΩ<Rb<181kΩ

The blocking time can also be set to a minimum of 9µs (typical) by selecting Rb=0Ω. The terminal TB must not
be left floating.

Description of Secondary Side Interfaces

General

Each driver’s secondary side (driver channel) is equipped with an 8-pin interface connector with the following
terminals (x stands for the number of the drive channel 1 or 2):

 1 x DC/DC output terminal VISOx
 1 x emitter terminal VEx
 1 x reference terminal REFx for overcurrent or short-circuit protection
 1x collector sense terminal VCEx

www.power.com/igbt-driver Page 11

SCALE™-2+ 2SC0435T

Preliminary Description & Application Manual

 1x active clamping terminal ACLx
 1x turn-on gate terminals GHx
 1x turn-off gate terminals GLx

All inputs and outputs are ESD-protected.

DC/DC output (VISOx), emitter (VEx) and COMx terminals

The driver is equipped with blocking capacitors on the secondary side of the DC/DC converter (for values,
refer to the data sheet /3/).

Power semiconductors with a gate charge of up to 3μC can be driven without additional capacitors on the
secondary side. For IGBTs or MOSFETs with a higher gate charge, a minimum value of 3µF external blocking
capacitance is recommended for every 1µC gate charge beyond 3µC. The blocking capacitors must be placed
between VISOx and VEx (C1x in Fig. 7) as well as between VEx and COMx (C2x in Fig. 7). They must be
connected as close as possible to the driver’s terminal pins with minimum inductance. It is recommended to
use the same capacitance value for both C1x and C2x. Ceramic capacitors with a dielectric strength >20V are
recommended.

If the capacitances C1x or C2x exceed 150µF, please contact Power Integrations' support service.

No static load must be applied between VISOx and VEx, or between VEx and COMx. A static load can be
applied between VISOx and COMx if necessary.

Reference terminal (REFx)

The reference terminal REFx allows the threshold to be set for short-circuit and/or overcurrent protection with
a resistor placed between REFx and VEx. A constant current of 150µA is provided at pin REFx.

Collector sense (VCEx)

The collector sense must be connected to the IGBT collector or MOSFET drain with the circuit shown in Fig. 7
in order to detect an IGBT or MOSFET overcurrent or short-circuit.

 It is recommended to dimension the resistor value of R

Active clamping (ACLx)

Active clamping is a technique designed to partially turn on the power semiconductor as soon as the collector­emitter (drain-source) voltage exceeds a predefined threshold. The power semiconductor is then kept in linear
operation.

Basic active clamping topologies implement a single feedback path from the IGBT’s collector through transient

voltage suppressor devices (TVS) to the IGBT gate. The 2SC0435T supports Power Integrations' Advanced

www.power.com/igbt-driver Page 12

SCALE™-2+ 2SC0435T

Preliminary Description & Application Manual

Active Clamping, where the feedback is also provided to the driver’s secondary side at pin ACLx: as soon as
the voltage on the right side of the 20Ω resistor (Fig. 7) exceeds about 1.3V, the turn-off MOSFET is
progressively switched off in order to improve the effectiveness of the active clamping and to reduce the
losses in the TVS. The turn-off MOSFET is completely off when the voltage on the right side of the 20Ω
resistors (Fig. 7) approaches 20V (measured to COMx).

It is recommended to use the circuit shown in Fig. 7. The following parameters must be adapted to the
application:

 TVS D

- Six 80V TVS with 600V IGBTs with DC-link voltages up to 430V. Good clamping results can be

- Six 150V TVS with 1200V IGBTs with DC-link voltages up to 800V. Good clamping results can be

- Six 220V TVS with 1700V IGBTs with DC-link voltages up to 1200V. Good clamping results can be

At least one bidirectional TVS (D2x) per channel must be used in order to avoid negative current
flowing through the TVS chain during turn-on of the antiparallel diode of the IGBT module due to its
forward recovery behavior. Such a current could, depending on the application, lead to undervoltage
of the driver secondary voltage VISOx to VEx (15V).

Note that it is possible to modify the number of TVS in a chain. The active clamping efficiency can be
improved by increasing the number of TVS used in a chain if the total threshold voltage remains at the
same value. Note also that the active clamping efficiency is highly dependent on the type of TVS used
(e.g. manufacturer).

Gate turn-on (GHx) and turn-off (GLx) terminals

These terminals allow the turn-on (GHx) and turn-off (GLx) gate resistors to be connected to the gate of the
power semiconductor. The GHx and GLx pins are available as separated terminals in order to set the turn-on
and turn-off resistors independently without the use of an additional diode. Please refer to the driver data
sheet /3/ for the limit values of the gate resistors used.

www.power.com/igbt-driver Page 13

SCALE™-2+ 2SC0435T

Preliminary Description & Application Manual

A resistor between GLx and COMx of 4.7kΩ (other values are also possible) may be used in order to provide a
low-impedance path from the IGBT/MOSFET gate to the emitter/source even if the driver is not supplied with
power. No static load (e.g. resistors) must be placed between GLx and the emitter terminal VEx.

Note however that it is not advisable to operate the power semiconductors within a half-bridge with a driver in
the event of a low supply voltage. Otherwise, a high rate of increase of VCE may cause partial turn-on of these
IGBTs.

How Do 2SC0435T SCALE-2+ Drivers Work in Detail?

Power supply and electrical isolation

The driver is equipped with a DC/DC converter to provide an electrically insulated power supply to the gate
driver circuitry. All transformers (DC/DC and signal transformers) feature safe isolation to EN 50178,
protection class II between primary side and either secondary side.

Note that the driver requires a stabilized supply voltage.

Power-supply monitoring

The driver’s primary side as well as both secondary-side driver channels are equipped with a local
undervoltage monitoring circuit.

In the event of a primary-side supply undervoltage, the power semiconductors are driven with a negative gate
voltage to keep them in the off-state (the driver is blocked) and the fault is transmitted to both outputs SO1
and SO2 until the fault disappears.

In case of a secondary-side supply undervoltage, the corresponding power semiconductor is driven with a
negative gate voltage to keep it in the off-state (the channel is blocked) and a fault condition is transmitted to
the corresponding SOx output. The SOx output is automatically reset (returning to a high impedance state)
after the blocking time.
