Title:
DIRECT-CURRENT POWER SUPPLY PARALLEL-MACHINE INPUT REVERSE CONNECTION PREVENTION CIRCUIT AND SERVER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/056917
Kind Code:
A1
Abstract:
A direct-current power supply parallel-machine input reverse connection prevention circuit and a server. The circuit comprises a first switch tube (Q1) and a second switch tube (Q2); a first end of the first switch tube (Q1) is used for being connected to a positive end of a first power supply (Power1), and a second end of the first switch tube (Q1) is connected to a positive input end of a first driving module (100); a first end of the second switch tube (Q2) is used for being connected to a positive end of a second power supply (Power2), and a second end of the second switch tube (Q2) is connected to a positive input end of a second driving module (200). When the second power supply (Power2) is connected reversely, the first switch tube (Q1) is closed, the second switch tube (Q2) is opened, thus preventing a current from flowing from the positive end of the first power supply (Power1) to a negative end of the second power supply (Power2); when the first power supply (Power1) is connected reversely, the first switch tube (Q1) is opened, the second switch tube (Q2) is closed, thus preventing a current from flowing from the positive end of the second power supply (Power2) to a negative end of the first power supply (Power1). The currents are blocked by means of the first switch tube (Q1) and the second switch tube (Q2), and the problem of internal device damage caused by power supply reverse connection during direct-current power supply parallel-machine input is effectively solved.
