More Information
Summary:The utility model discloses an Ethernet power supply system, which comprises power supply equipment and power receiving equipment, the power receiving equipment comprises a signal response unit, a load unit and a power maintaining circuit, and the power maintaining circuit is used for monitoring load current of the load unit and generating dummy load current based on the load current and the power maintaining current; a current sampling module is used for sampling a load current to obtain a sampling current in proportion to the load current, a current comparison module is used for obtaining a first current signal based on a power maintaining current and the sampling current, and an MPS current generation module is used for generating a dummy load current based on the first current signal. The dummy load current is used for maintaining the current required by the electric power from the power supply equipment to the power receiving equipment, and the power supply equipment can still detect the existence of the
