Abstract

Provided is an inverter control device that makes it possible to improve the cosmic ray resistance of an inverter without increasing cost and system weight. An inverter control device 600 comprises: a voltage application total time determination unit 602 for determining a total voltage application time of each of a plurality of inverters 201, 202, 207, and 208; an operation pattern determination unit 603 for receiving as an input operation information of a flight vehicle 501, determining an operation pattern of the flight vehicle 501, and outputting the operation pattern to the voltage application total time determination unit 602; an inverter control unit 604 for controlling the plurality of inverters 201, 202, 207, 208 according to a command of the voltage total time determination unit 602, and electric current information and voltage information of the plurality of inverters 201, 202, 207, 208; and a switching control unit 605 for controlling the connection and opening of the plurality of inverters 201, 202, 207, 208 and an electric power supply 300 of the plurality of inverters 201, 202, 207, 208, according to information of the inverter control unit 604.
