Abstract

See full text

A method for detecting a ground fault in an inverter using leg-shunt resistors is provided. The method includes detecting output currents of three phases of the inverter, determining whether or not a voltage utilization of the inverter is not less than a preset allowable voltage level, and determining an occurrence or non-occurrence of the ground fault in the inverter.
