    • PROBLEM TO BE SOLVED: To provide an inverter that controls processes in a control circuit that controls an inverter unit by making it synchronize with the period of an AC voltage which is an output. SOLUTION: The inverter is provided with an inverter circuit, a drive circuit, and a control circuit. This control circuit monitors the inverter circuits, controls the drive circuits, and performs any one of a first process that generates data showing the state of the inverter, a second process that generates data for controlling a drive source of the inverter, a third process for detecting an error in the inverter, and a fourth process that generates data for controlling the period of the AC voltage, in each of the first to fourth periods obtained by dividing into quarters one period of the AC voltage that is the output.
