Title:
DISCHARGE CIRCUIT OF SMOOTHING CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2023/145466
Kind Code:
A1
Abstract:
A discharge circuit (40) causes a smoothing capacitor, which smooths a DC voltage, to discharge via a plurality of resistive elements (41) mounted to a substrate (50). The discharge circuit comprises a series-connected body in which at least three resistive elements (41 (11-15)) that are disposed so as to be spaced in a first direction (X1) are connected in series by wiring (47 (11-14)). The resistive elements included in the series-connected body have respective resistance values that decrease as the resistive element is closer to the center in the first direction. Resistive elements that are included in the series-connected body and that are adjacent in the first direction have differing positions in a second direction (X2) which is perpendicular to the first direction.
