Patent ID: 11929662
Assignee: SONY GROUP CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
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.
