Title:
SWITCHING CIRCUIT AND METHOD FOR CONTROLLING SWITCHING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/206033
Kind Code:
A1
Abstract:
Provided are: a switching circuit which can suppress generation of chattering and leakage current while suppressing generation of arcing; and a method for controlling the switching circuit. In a switching circuit 2, a semiconductor switch 10, a serial mechanical switch 11, and a parallel mechanical switch 12 are mounted on a circuit board 13. When the switching circuit 2 is operated to be powered off from on, the parallel mechanical switch 12 is turned off (step 1). Then, the semiconductor switch 10 is turned off (step 2). Then, the serial mechanical switch 11 is turned off (step 3). Through the steps 1-3, all the switches 10-12 are turned off, whereby the switching circuit 2 is powered off.
