Abstract
The inverter comprises a diode bridge () that rectifies an inputted three-phase AC voltage into a DC voltage, an inverter section () that converts the DC voltage converted by the diode bridge () into an AC voltage and outputs the resulting voltage, an LC filter that has an inductor Lconnected between one output terminal of the diode bridge () and one input terminal of the inverter section and a capacitor Cconnected across the input terminals of the inverter section, a voltage detecting section () that detects cross terminal voltage of the inductor L, and a control section () that controls the inverter section (). The control section () controls the inverter section () so that the transfer characteristic of the I/O voltage of the inverter section () becomes a characteristic of the first-order lag system on the basis of the cross terminal voltage of the inductor Ldetected by the voltage detecting section ().
