The inverter controller includes a deviation arithmetic circuit which calculates the deviation between the current command (reference) and the output current, a vector angle arithmetic circuit which calculates the deviation current vector angle on the basis of the deviation calculated by this deviation arithmetic circuit, and a switching sequence logic circuit which selects the switching signal on the basis of the deviation current vector angle calculated by the vector angle arithmetic circuit and its own switching signal being output or on the basis of the deviation current vector angle and its own switching signal and the switching signal output previously, and obtains an output current by controlling self-turn-off switching devices on the basis of the switching signal output by the switching sequence logic circuit.
