Description
The STEVAL-IHM023V3 evaluation board implements a 1 kW three-phase motor control application featuring L6390 high and low-side driver and the STGP10H60DF IGBT. The evaluation board is an AC-DC inverter that generates a three-phase waveform for driving two- or three-phase motors such as induction motors or PMSM motors up to 1000 W, with or without sensors. The STEVAL-IHM023V3 is a universal, fully evaluated and populated design consisting of a three-phase inverter bridge based on STMicroelectronics’ 600 V IGBT STGP10H60DF in a TO-220 package mounted on a heatsink, and the L6390 high-voltage high-side and low-side driver featuring an integrated comparator for hardware protection features such as overcurrent and overtemperature. The driver also integrates an operational amplifier suitable for advanced current sensing. Thanks to this advanced characteristic, the system achieves accurate and fast conditioning of the current feedback, addressing the typical requirements of fieldoriented control (FOC). The board has been designed to be compatible with a single-phase mains, supplying from 90 VAC to 285 VAC or from 125 VDC to 400 VDC for DC voltage. With reconfiguration of the input sourcing, the board is suitable also for low-voltage DC applications up to 35 VDC.
