Shunt based Ground Fault Protection for Inverters Powered from 220Vac Supply Reference Design
This referene design detects ground fault in inverter-based drives. Inverter current is measured on both DC-positive and DC-negative bus using shunt resistors. Current on DC-positive bus is measured using INA170 which is powered by a low-side switched buck converter. Current on DC-negative bus is sensed using precision op amps. The difference between the two measured currents is compared against a fixed threshold to determine the ground-fault condition using high-speed comparators.
