Leakage protection circuit with noise filter

Abstract

A leakage protection circuit with noise filtering, comprises a leakage protection circuit. The input of the leakage protection circuit is connected in series with a noise filtering circuit before being connected to the power supply, and the output of the leakage protection circuit is connected to the electrical equipment. When a leakage occurs in the electrical device, the differential signals generated in the power line are directly detected by the leakage protection circuit, and allow for timely power cutoff. The operation will not be affected by the functioning of the noise filtering circuit and help to avoid false trigger and improve the response time of the leakage protection circuit.
