Thermal Protection of IGBT Modules for HEV and EV Traction Inverters Reference Design
Overview
| Topology | FlyBuck (Double Buck) |
| Input voltage | 12 V |
| Output 1 | -9 V / 0.2 A |
| Output 2 | 15 V / 0.2 A |
| IC revision | A |
Description
This reference design is a temperature sensingsolution for IGBT thermal protection in hybrid electricvehicle and electric vehicle (HEV and EV) tractioninvertersystems. The solution monitors the IGBTtemperature through the NTC thermistor that isintegrated inside of the IGBT module and providesthermal shutdown to the IGBT gate drivers once theNTC thermistor temperature rises above theprogrammed threshold. The design includes the IGBTisolated gate drivers, NTC signal conditioning, I2Cinterface and isolation, and a load resistor that enablesthe system to run independently under high powerratings
Features
- Designed for Traction Inverters With Rated Currentup to 300 A and DC Bus Voltage up to 400 V
- An IGBT Half-Bridge Evaluation Platform ThatIncludes Gate Driver, Isolation, NTC SignalConditioning Circuit, Interface to MCU, and LoadResistor
- Push-Pull Current Boost at Gate Driver ThatEnables 10-A Source and 10-A Sink Peak GateCurrents
- One Multichannel ADC and one Isolation IC forConditioning Multi NTCs in Inverter System
- 8-kV Reinforced Isolation and CMTI Greater Than50 kV/μsREMARK:SchematiC,BOM with pdf IS ADDED
