Abstract

The invention provides a power supply method, a device and a system, wherein the power supply system comprises a main circuit power supply circuit, an auxiliary circuit power supply circuit, a controlcircuit and a switching device, wherein, the auxiliary circuit power supply circuit is connected with the control circuit and used for supplying a power supply voltage to the control circuit; The control circuit is connected with the main circuit power supply circuit via the switching device, and is used for controlling the on/off of the switching device. The adoption of that technical scheme, ina related art, the auxiliary winding is added to the transformer of the main circuit power supply circuit to supply power to the control circuit in the anti-backflow circuit, As a result, the transformer design of the main circuit power supply circuit is complicated, which is not conducive to the problem of flexible design and optimization efficiency of the transformer, and can effectively solvethe power supply problem of the control circuit of the anti-backflow circuit, at the same time, the design flexibility of the main circuit power supply circuit is improved, which is conducive to the efficiency optimization of the main circuit design.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a power supply method, device and system. Background technique [0002] The redundant power supply system is a highly reliable power supply system. The power supply system is composed of multiple power supply modules connected in parallel. It is mostly used in servers, computer room systems and other equipment. When the power supply current is reversed and damaged, an anti-reverse circuit is designed at the output high voltage end, that is, an ORING circuit, and a switching device and a control part are added at the output high voltage end. When a module in the parallel power supply is abnormal, the control circuit Control the timely disconnection of switching devices to realize the function of preventing current backfeeding. [0003] figure 1 It is a structural schematic diagram of an anti-backfeed circuit in the related art. Such as figure 1 As shown, the anti-backfeed ci...
