Title: INVERTER DEVICE
Abstract:
An inverter (10A) has a plurality of switching elements, the states of which are each switched by a pulse signal supplied in accordance with a power grid voltage (Vac). The inverter (10A) is provided with: a switching circuit (11) that converts an input DC voltage to an AC voltage and outputs the AC voltage to a pair of output lines (X1, X2); a filter circuit (13) having output coils (L1, L2) inserted in the output lines (X1, X2); a current detection sensor (14) that detects the current flowing through the output coils (L1, L2); and a high-speed pulse control circuit (15) that, when an absolute value of the detected current is a threshold value or more, stops the supply of the pulse signal to the switching circuit (11).
