REF_80VDC_3.5KW_OPE2 3.5 kW BLDC motor drive system solution for outdoor power equipment (OPE) and LEVs operating from a 72-80 V battery pack

Overview

The REF_80VDC_3.5KW_OPE2 reference board is a high efficiency BLDC/PMSM three phase motor drive solution based on Infineon's PSOC Control 3 advanced M33 based microcontroller. It is capable of supporting multiple control schemes including sensor-less field oriented control (FOC). It produces sinusoidal motor phase current up to 100 Amps peak and 40 Amps RMS continuous motor drive power of 2.5 kW. It operates with Infineon's motor control suite.
