Classification: CPC H | IPC H

Claim 9:
10. A control method that is performed by a power circuit that includes at least a first power supply unit and a second power supply unit, the first power supply unit including a first input section, a first AC voltage generator that generates a first AC voltage on a basis of an input voltage input to the first input section, a first rectification-and-smoothing section that rectifies and smooths the first AC voltage, and a first isolation section that includes a capacitor and is provided between the first AC voltage generator and the first rectification-and-smoothing section, the second power supply unit including a second input section, a second AC voltage generator that generates a second AC voltage on a basis of an input voltage input to the second input section, a second rectification-and-smoothing section that rectifies and smooths the second AC voltage, and a second isolation section that includes a capacitor and is provided between the second AC voltage generator and the second rectification-and-smoothing section, the control method comprising
performing, by a controller, control such that the second AC voltage generator generates the AC voltage of which a phase is obtained by inverting a phase of the AC voltage generated by the first AC voltage generator.
