Abstract

The invention discloses an anti-impact circuit for power supply equipment, the power supply equipment and an Ethernet power supply system, which are higher in reliability. The anti-impact circuit comprises an energy storage module and a switching module which is switched off at a power supply stage of the power supply equipment. A first end of the energy storage module is connected to a positive output end of the power supply equipment. A second end of the energy storage module is connected with a first end of the switching module. A second end of the switching module is connected with a negative output end of the power supply equipment.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an anti-shock circuit of power supply equipment, power supply equipment and an Ethernet power supply system. Background technique [0002] POE (Power Over Ethernet, Power over Ethernet) technology is a technology that uses network cables to transmit power to provide DC power for network terminal equipment. [0003] In the prior art, POE systems such as figure 1 As shown, it includes power supply equipment and power receiving equipment, wherein the power supply equipment includes system power supply, controller, NMOS transistor Q1 (N-Metal-Oxide-Semiconductor FieldEffect Transistor, N-channel Metal-Oxide-Semiconductor Field Effect Transistor) and resistors R1. The working stages of the existing power supply equipment are divided into three stages: detection stage, classification stage and power supply stage. The operations of the three stages are mainly realized by the co...
