Title:
SWITCHING MODULE AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/131741
Kind Code:
A1
Abstract:
A switching module (1) includes: mechanical relays (111A, 121A, 131A, 111B, 121B, 131B); semiconductor switches (112A, 112B, 112A, 122B, 132A, 132B); voltage detection units (151, 152, 153) that detect an input voltage input into a power conversion unit (2); and a control unit (18). When a determination is made that a waveform of the input voltage during a first determination period is abnormal, the controller (18) outputs an open command signal to the mechanical relays (111A, 121A, 131A) that each correspond to a power supply that is electrically connected to the power conversion unit (2) and, thereafter, when a determination is made that the waveform of the input voltage in a second determination period is normal, outputs a close command signal to the mechanical relays (111A, 121A, 131A).
