Active continuous dc power supply insulation malfunction detection circuit

An active continuous DC power supply insulation malfunction detection circuit, comprising:

• at least one leakage current detection unit located on at least one loop of a power supply system for detecting and measuring leakage current value of the loop;
• at least one positive voltage terminal compensation unit which includes one end connected to a positive voltage terminal of the power supply system and another end connected to a ground terminal, and a first one-way discharger, a first resistor and a first power source unit providing DC power that are coupled in series, the first one-way discharger and the first power source unit being forward conducted;
• and
• at least one negative voltage terminal compensation unit which includes one end connected to a negative voltage terminal of the power supply system and another end connected to the ground terminal, and a second one-way discharger, a second resistor and a second power source unit providing DC power that are coupled in series, the second one-way discharger and the second power source unit being forward conducted.
