Beschreibung
Zusammenfassung:	The utility model relates to the field of chargers, and particularly discloses an auxiliary power supply module for a bidirectional DC charger, which comprises an input end, a first output end and a second output end, the input end is connected with an external power supply, the first output end is connected with a DC/DC circuit to provide insulation detection voltage for the bidirectional DC charger, and the second output end is connected with an external power supply. The second output end is connected with the anode of a diode D2, and the cathode of the diode D2 is connected with the DC/DC circuit and provides auxiliary power supply for the DC/DC circuit during reverse working. In a reverse off-grid mode, the power level DC/DC circuit does not need to output insulation detection voltage required by the electric automobile, the insulation detection voltage is directly provided by the auxiliary power supply module, after the scheme of the auxiliary power supply module is fixed, the no-load loss is basically
