METHOD FOR CONTROLLING INVERTER

摘要

In some embodiments, an inverter control apparatus and a method for controlling the same are provided. The inverter control apparatus may speed up the discharging of the residual energy at an inverter driven with an input power when a safety signal is input to the inverter. The inverter control apparatus may include an input power switchgear supplying an input power to the inverter according to switching operation; an I/O unit inputting a safety signal to the inverter according to a user control input and outputting a failure output relay signal to the input power switchgear when the safety signal is generated; and a controller performing speeding up the discharge of residual energy at the inverter when the input power is interrupted.
