The STEVAL-CTM010V1 board embeds two sensorless 3-phase motor drives, plus a single stage digital PFC boost topology, all controlled by the STM32F303RB ARM based microcontroller. The ST FOC MC SDK firmware library enables this complete hardware and software solution, featuring FOC dual motor sensorless and PFC CCM mode. The inverter stages are based on SLLIMM™ IPM series of intelligent power modules for compact, high-performance AC motor drives in a simple, rugged design. It combines new ST proprietary driver ICs with an improved short-circuit rugged trench gate field-stop (TFS) IGBT, making it ideal for motor drives operating up to 20 kHz in hard-switching circuits.
The PFC section is based on the STTH30AC06C ultra-fast high voltage rectifier and STGWT20H65FB trench gate field-stop IGBT.
The board embeds the 2nd generation SLLIMM STGIB10CH60TS-L and STGIPQ3H60T-HZ intelligent power modules, which are tailored to drive motors for compressors and fans in outdoor units. The STEVAL-CTM010V1 is therefore ideal for evaluating room air conditioner solutions able to meet new efficiency standards requiring digital PFCs, and any single or dual motor application with power factor correction.
