Abstract
Disclosed are a high-voltage protection circuit, a high-voltage protection method and a power supply. The high voltage protection circuit comprises a main relay, an auxiliary relay, a first resistor, a second resistor, a first capacitor and a second capacitor, wherein one end of the main relay is connected to the input port of a live line, and the other end thereof is connected to the output port of the live line; one end of the auxiliary relay is connected to the input port of the live line, and the other end thereof is connected between the first resistor and the second resistor; one end of the first capacitor is connected to the output port of the live line, and the other end thereof is connected to a neutral line parallel to the live line; the second capacitor is connected to both ends of the main relay in parallel; and the second resistor and the first resistor are connected between the input port and the output port of the live line in series in sequence. The present invention can effectively solve the problem that quick recovery cannot be achieved in an energy-saving mode, so that the system achieves high efficiency and energy saving, and can ensure high-voltage protection i…
