Title:
SWITCHING CIRCUIT AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/044848
Kind Code:
A1
Abstract:
The present application provides a switching circuit and a power supply device. The switching circuit comprises at least one switching tube, a metal unit (20), and a first branch (21). The metal unit (20) is disposed on the switching tube. The first branch (21) is electrically connected between the switching tube and the ground, and/or the first branch (21) is electrically between the metal unit (20) and the ground. The first branch (21) comprises a first capacitor (C1), and the first capacitor (C1) is used for discharging radiation interference. In this way, radiation interference can be reduced while maintaining the heat dissipation effect, and the volume is also relatively small.
