STMicroelectronics STEVAL-CTM015V1 3-Phase Motor Drive Eval Kit
STMicroelectronics STEVAL-CTM015V1 3-Phase Motor Drive Evaluation Kit provides a complete solution for a 3-phase switched reluctance motor (SRM) drive based on an asymmetric half-bridge flexible converter topology. The kit consists of the STEVAL-CTM015A1 driver board, the STEVAL-CTM015A2 power board, and a pre-assembled 1K/W heat sink. The STEVAL-CTM015A1 driver board features a DC-DC power supply based on the VIPER26L, LD1117S50, and LD1117S33C, an STM32F303CBT6 as the MCU, and L6395D high voltage, single-chip high/low-side gate drivers for N-channel power MOSFETs or IGBTs. The STEVAL-CTM015A2 power board features an insulated metal substrate (IMS), NTCs for thermal protection, decoupling gate resistors for each IGBT, LMV331I comparators for overcurrent protection, an STGB30H60DFB trench gate field-stop, and STTH15RQ06 Turbo 2 soft ultrafast recovery diode.
The STMicroelectronics STEVAL-CTM015V1 Evaluation Kit features a three-shunt resistor current sensing network based on the TSV991IL, but can also host three Insulated Current Sensors (ICSs). Soft-chopping speed control firmware, based on the STM32F303CBT6 microcontroller, is
available.
