- TIDA-00442, Shunt based Ground Fault Protection for Inverters Powered from 220Vac Supply Reference Design. The TIDA-00442 design provides a reference solution for detecting 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 low side switched buck converter. Current on DC negative bus is sensed using precision Op-Amp. The difference between the two measured currents is compared against a fixed threshold to determine the ground fault condition using high speed comparators
