2RT0435T
Target Description & Application Manual
Two layer Base Board exclusively assembled with through-hole components
for 2SC0435T SCALE™-2 driver for 1200V and 1700V IGBT modules or
MOSFETs with an electrical interface for 2-level, 3-level and multilevel
converter topologies with paralleling capability
Abstract
The 2RT0435T is a dual-channel Base Board for CONCEPT's SCALE™-2 driver core 2SC0435T, a low-cost
SCALE-2 dual-driver core for the reliable driving and safe operation of IGBTs. This Base Board is assembled
only with THT-components using a two-layer PCB.
The Base Board is suitable to drive almost all available dual IGBT modules up to 1700V like 62mm IGBT
modules, 130mm x 140mm IGBT modules and others. The plug-and-play capability (only the gate resistors
are missing) makes it ready to operate immediately after mounting. The user needs invest almost no effort in
designing or adjusting it to a specific application.

Page 3: System Overview
Target Description and Application Manual System Overview The 2RT0435T are Base Boards for the driver 2SC0435T. 2SC0435T are SCALE-2 driver cores based on the SCALE-2 technology developed by CONCEPT /1/. This is a set of application-specific integrated circuits (ASICs) that cover the main range of functions needed to design intelligent gate drivers. The SCALE-2 driver chipset is a further development of the proven SCALE technology /2/. -
Page 4: The Six Steps To Success
The following steps point out the easy way to use 2RT0435T Base Boards in power converters: 1. Choose a suitable Base Board/driver When applying 2RT0435T Base Boards, you should note that the gate resistors are not assembled. They must be assembled according to the used IGBT module before start of operation. - Page 5 2RT0435T Target Description and Application Manual Even if only single IGBTs are tested, all the system’s gate drivers must be supplied with energy. All the other IGBTs are then kept in the off state by applying negative gate voltages. This is particularly important when switching the IGBTs under test.

IGBTs against overvoltage during turn-off. It is particularly relevant when turning an IGBT off in cases of high DC-link voltage and collector current or short circuit. The 2RT0435T Base Boards also allow parallel operation of IGBT modules in order to increase the system power (see “Parallel connection of 2RT0435T”... -
Page 12: Ce Monitoring / Short-Circuit Protection
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 2RT0435T Base Boards support CONCEPT’s Advanced Active Clamping based on this principle: when active clamping is activated, the turn-off MOSFET of the driver is switched off in order to improve the effectiveness of the active clamping and to reduce the losses in the TVS. -

/6/. 3-level and multilevel topologies If the 2RT0435T Base Boards are to be used in 3-level or multilevel topologies, please refer to the application note AN-0901 /8/ on www.IGBT-Driver.com/go/app-note. Low-inductance layout The active-clamping function should not lead anyone to forget about the inductances of the power stack. For several reasons, it is recommended to reduce the DC-link stray inductance to about 30nH…100nH depending... -
