1 Abstract

This application note describes an evaluation board for the flowPACK 1 H6.5 module. A gate

drive optocoupler (ACPL-352J), connectors, terminals and the like are included for testing the

flowPACK 1 H6.5 module.

2 Evaluation board order number

Evaluation board order number: EVA-L98x-PCB

Evaluation board is delivered without power module, which should be ordered separately.

Vincotech can assemble the power module in the PCB on request.

3 Target application

The target application is single-phase PV inverters up to 10 kW.

An example of application conditions in Japan follows:

1) VCC=350V

2) Vac=202Vrms

3) fc=20kHz

4) Io=15Arms～50Arms

An example of application conditions in Europe/Asia follows:

1) VCC=400V

2) Vac=240Vrms

3) fc=20kHz

4) Io=15Arms～50Arms

The above application is given for reference only. The H6.5 evaluation board cannot guarantee

the module's suitability for it.

4.3.2 The operating waveform (simulation)

The figure below shows the simulated waveform.

4.3.3 An example of the tested waveform

The figure below shows the tested waveform at around VCE and VGE of T12, T21 and output

current (Iout). It examines the performance in three-level operation.

5 Gate driver for the IGBT module

Broadcom driver ACPL-352J

Please refer to the broadcom datasheet “pub-005817_DS_ACPL-352J_2016-08-29” for

specification details.

5.1 Standard gate resistance

Rgon,Rgoff = 3.9ohms(*1)

Gate drive voltage VG=+15V/-6V

*1) Standard value on this board

5.2 Another gate resistance

Rgon,Rgoff =5.7ohms(*2)

Gate drive voltage VG=+15V/-15V

*2) When the negative gate voltage is -15V, the gate resistance must be adjusted to 5.7

ohms.

*1),2) Rgon,Rgoff=((VG+)-(VG-))/Ipeak-0.3ohms

VG+ signifies a positive gate voltage. VG- indicates a negative gate voltage.

Gate resistance values are determined by the peak current (Ipeak) and the ACPL-352J's

internal resistance.

6 Connector

Seven connectors are used for the control signal, UVLO (under voltage lock out) and power

supply.

Connector no. Name Content

CN1 Control circuit1 Control signal for T12&T21, UVLO, 5V power supply



CN4 NTC thermistor

CN11 Drive power supply1 Positive and negative drive power supply for T12&T21




7 Protection function

7.1 UVLO

Insufficient gate voltage to the IGBT can increase its turn-on resistance, resulting in

considerable power loss and heat dissipation that can damage the IGBT. The ACPL-352J

constantly monitors the VDD2 output power supply. When the output power supply is lower

than the under voltage lockout (UVLO) threshold, the gate driver output shuts off to protect

the IGBT from low-voltage bias. During power-up, the UVLO feature sets the gate driver

output to a low value to prevent unwanted turn-on at a lower supply voltage.

Please refer to the Broadcom datasheet “pub-005817_DS_ACPL-352J_2016-08-29.”

UVLO threshold Type

VULO+ 12.9V

VULO- 11.8V

7.2 Over-current protection

The H6.5 IGBT series does not come with OC protection because H6.5 IGBTs are not

susceptible to short circuits.


8 Isolation, creepage and air clearance distance

8.1 Isolation voltage

4000V, 2 seconds between the primary and secondary circuit

8.2 Creepage and air clearance distance

a) Creepage distance: 6 mm

b) Air clearance distance: 4 mm


9 Circuit connections

The diagram below shows the control signal and power supply connections, and gives the

names of terminals.

Either DC Capacitor A (on the left) or DC Capacitor B (on the right) or both can be connected.

Snubber capacitors (C35 & C36) are connected to reduce the surge voltage at switching.

The circuit at the test pin has a greater inductance than the H6.5 IGBT module pin's terminal.

The waveform may display some ringing because of this inductance.

12 PCB Assembly Drawing


13 Layout of PCB

The following section illustrates four layers of PCB patterns (pages 10 to 13).

Both DC+ sides are connected in the H6.5 IGBT series' internal circuit.

The H6.5 IGBT series' DC-1 and DC-2 are connected in the PCB pattern (see pages 12 and 13).

DC+ and DC- have two layers of the PCB pattern to secure the current flow area and lower

inductance.
