CPC H02M 1/0038 (2021.05) [H02M 1/14 (2013.01); H02M 3/33571 (2021.05)] | 10 Claims |
1. A power circuit, comprising: 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 power circuit being configured 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.
