Abstract

The embodiment of the invention provides a power conversion circuit, a power supply and electronic equipment. The power conversion circuit can convert a power supply voltage from power supply equipment into a power supply voltage suitable for power receiving equipment, and supplies power to the power receiving equipment. Meanwhile, the power conversion circuit adopts floating output to supply power to the power receiving equipment, so that surge and / or static electricity transmitted to the power receiving equipment can be effectively reduced, the anti-surge and / or anti-static capacity of the power receiving equipment is improved, and the risk of breakdown of the power receiving equipment is avoided. Besides, even if the power supply voltage provided by the power supply equipment is changed, the power supply to the power receiving equipment is difficult to influence, namely, the power conversion circuit can ensure the power supply stability to the power receiving equipment.

Description

technical field [0001] The embodiments of the present application relate to the technical field of power supplies, and in particular, to a power conversion circuit, a power supply, and electronic equipment. Background technique [0002] In the POE (Power over Ethernet, Power over Ethernet) system, the power supply equipment (PSE, Power Sourcing Equipment) transmits network data to the powered device (PD, Powered Device) through the network cable, and also supplies power to the powered device through the network cable. [0003] At present, in the power solution based on PoE technology, the power supply equipment provides the power supply voltage to the power conversion circuit through the network cable, and the power conversion circuit performs DC conversion and constant voltage processing on the power supply voltage input through the network cable to obtain the power receiving end equipment. Applicable constant voltage, and provide the constant voltage to the powered equipme...
