Abstract:
The present disclosure relates to an overcurrent protection inverter, and more particularly, to an inverter, which uses a leg-shunt resistor so as to detect an instantaneous maximum output current and an AD current, thereby performing an inverter protection operation. The present disclosure detects the instantaneous maximum output current and detects the AD current from the leg-shunt resistor so as to perform an overcurrent protection operation when an overcurrent occurs in the entire inverter operation section, thereby enabling protection of the inverter.
