Title:
CONNECTOR, SWITCHING POWER SUPPLY, AND COMMUNICATION POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/218421
Kind Code:
A1
Abstract:
A connector (120), a switching power supply (10), and a communication power supply system provided by the present disclosure, the connector (120) comprising a first connecting piece (121), a second connecting piece (122), a capacitor pre-charging circuit (123) and a control circuit (124). The first connecting piece (121) can be detachably connected to the second connecting piece (122); the first connecting piece (121) is connected to the output end of a power supply apparatus (110); the second connecting piece (122) is connected to a direct current (DC) bus (20); the capacitor pre-charging circuit (123) and the control circuit (124) are both disposed on the first connecting piece (121); the capacitor pre-charging circuit (123) is connected to a capacitor circuit (111); and the control circuit (124) is used to control the power supply apparatus (110) to power on and off. On the basis of the foregoing, during the process of inserting the first connecting piece (121) into the second connecting piece (122), the DC bus (20) first charges the capacitor circuit (111) by means of the capacitor pre-charging circuit (123), and the control circuit (124) then controls the power supply apparatus (110) to power on. Moreover, when the first connecting piece (121) is pulled out from the second connecting piece (122), before the power supply apparatus (110) is disconnected from the DC bus (20), the control circuit (124) first controls the power supply apparatus (110) to power off. It can be seen that the present disclosure can reduce the power consumption of the switching power supply (10), and can simplify the structure of the switching power supply (10).
