STMicroelectronics STGB30H65FB | Demoboard STEVAL-CTM015V1

1 kW, 400 VDC three-phase switched reluctance motor drive

Overview

TopologyFull-Bridge Converter symmetrical isolated
IC revision1

Description

The STEVAL-CTM015V1 evaluation kit provides a complete solution for a three-phase switched reluctance motor (SRM) drive based on asymmetric half bridge flexible converter topology. The kit consists of the STEVAL-CTM015A1 driver board, the STEVAL-CTM015A2 power board and a 1 K/W heat sink already assembled.The driver board features a DC-DC power supply based on VIPER26L, LD1117S50, LD1117S33C, STM32F303CBT6 as MCU, and L6395D high voltage, single-chip high and low-side gate drivers for N-channel power MOSFETs or IGBTs.The power board features an insulated metal substrate (IMS), NTCs for thermal protection, decoupling gate resistors for each IGBT, LMV331I comparators for overcurrent protection, STGB30H65FB trench gate field-stop, and STTH15RQ06 Turbo 2 soft ultrafast recovery diode.By default, the STEVAL-CTM015V1 features insulated current sensors (ICS) for phase-current reading, but a three-shunt resistor current-sensing network based on TSV991IL is also available.Soft-chopping speed control firmware, based on STM32F303CBT6 microcontroller, is available.
