Claim:
1. A power converter comprising: inverters, AC sides of the inverters being connected in parallel; and a controller configured to control total output power of the inverters by controlling output power of at least one of the inverters by a control command in a control cycle shorter than a shortest communication cycle which allows communication of the control command with each of the inverters and determine a first power command value and a second power command value, the first power command value being lower than a proportional division power value obtained by proportionally dividing a required power value required as the total output power of the inverters based on respective rated outputs of the inverters, the second power command value being higher than the proportional division power value, wherein the controller controls output powers of the inverters at the first power command value and the second power command value determined by the controller.
