US 12,199,523 B2 · Power control apparatus

Abstract

A power control apparatus, comprising: a first wiring and a second wiring connected to a power source; a first capacitor connected to the first wiring and the second wiring; an electrical component including a plurality of switches connected in parallel with the first capacitor through the first wiring and the second wiring; and a second capacitor which is connected to one of the first wiring and the second wiring and is connected to a reference potential portion having a constant potential, wherein an impedance of a first conducting path between another side connection point, which is connected to the first capacitor, of the other one of the first wiring and the second wiring and the power supply not through the first capacitor, is higher than an impedance of a second conducting path between the another side connection point and the second capacitor through the first capacitor.
