摘要
Provided is a grid-connected inverter device that realizes a stable switching operation in a small current region near the zero cross of a system voltage and has little loss. In a grid-connected inverter device having a bridge circuit, a filter circuit, and a control means for controlling the bridge circuit, and supplying power obtained from a DC power source to a commercial system through the bridge circuit and the filter circuit in this order, the bridge circuit Consists of a plurality of switches, and the control means controls the switches so that the distortion of the current flowing through the commercial system is suppressed from the period before the predetermined period until the predetermined period has elapsed with the zero cross point of the voltage of the commercial system as a base point. Mode 1 and Mode 2 in which the switch is controlled so as to reduce the loss of the switch in a period from the elapse of a predetermined period to the next predetermined period.
