Abstract

See full text

This application provides an insulation resistor detection circuit, which includes a state control unit, which is connected between a positive electrode and a negative electrode of a power supply of a to-be-detected apparatus; a first voltage division branch that is connected in parallel to a first capacitor to obtain a first voltage waveform, a second voltage division branch that is connected in parallel to a second capacitor to obtain a second voltage waveform; and a processor that is connected to the state control unit, the first voltage division branch, and the second voltage division branch; determines a next switching moment based on the first voltage waveform and the second voltage waveform that are at a current moment; and control, at the next switching moment, the state control unit to switch a state.
