STEVAL-IHM040V1 STMicroelectronics

STEVAL-IHM040V1 BLDC/PMSM driver demonstration board based on STM32 and the SLLIMM nano Data brief Features Extended AC input mains range: 115 or 230 VAC nominal at 50/60 Hz, or DC input voltage between 150 and 350 VDC Output current: 0.5 A to the motor RMS Power stage: 3-phase inverter bridge implemented using the STGIPN3H60 SLLIMM- nano intelligent power module RoHS compliant Description The STEVAL-IHM040V1 is a 3-phase permanent magnet brushless motor driver designed to drive a motor using either the six step or field oriented control (FOC) commutation technique. The board can operate from an AC mains of either 115 or The third block is the power supply, which 230 V nominal at 50/60 Hz, or from a DC input AC employs the VIPER16 to convert the high voltage voltage between 150 and 350 VDC. The board DC bus to a regulated 15 V supply that supplies can supply a continuous output current of 0.5 the SLLIMM and analog circuitry on the board. A to the motor. RMS The 15 V supply also supplies an L78L33 linear The circuit consists of three main blocks. The first regulator that provides the 3.3 V logic supply for is the digital control block, which uses the the microcontroller. STM32F100C8T6 microcontroller to implement Two firmware control programs are available, one the control algorithms and to generate the control for six steps and one for FOC, which run on the signals for the power stage. The main outputs of same hardware platform. the control block are the signals for the power stage. The second block is the power stage, a 3-phase inverter bridge implemented using the STGIPN3H60 SLLIMM-nano intelligent power module. The SLLIMM includes the 6 IGBTs, gate drivers and level shift required to interface the logic signals from the digital control to the motor terminals. The SLLIMM also provides a hardware overcurrent shutdown and an op-amp used to scale and bias the current sensing.
