Product overview

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, STGB30H60DFB trench gate field-stop, and STTH15RQ06 Turbo 2 soft ultrafast recovery diode.

By default, the STEVAL-CTM015V1 features the three-shunts resistors current sensing network based on TSV991IL, but it can also host three Insulated Current Sensors (ICSs).

Soft-chopping speed control firmware, based on STM32F303CBT6 microcontroller, is available.
