Title:
Inverter output ground fault detection method
Document Type and Number:
Japanese Patent JP6329194
Kind Code:
B2
Abstract:
The present invention relates to a method for detecting a ground fault in an inverter. The method for detecting the ground fault in the inverter in a current detection using leg-shunt resistors 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 on the inverter.
