The present invention belongs to the technical field of vehicle-borne power supplies and particularly relates to the novel power supply circuit for an electrical power maintenance vehicle. The solved technical problem is that the invention provides the novel power supply circuit with a small volume and high efficiency, and the transformation ratio of a high-frequency transformer can be reduced. The employed technical scheme is that the novel power supply circuit for the electrical power maintenance vehicle comprises an input module, a high-frequency isolation module and output module, the output end of the input module is connected to the input end of the high-frequency isolation module, the output end of the high-frequency isolation module is connected to the input end of the output module, the input module comprises a power supply module, a control module and a boost module, the power supply module comprises a main DC power supply U1 and a backup DC power supply U2, the control module comprises a first control unit P1 and a relay unit KM1, and the boost module comprises a tapped inductor L1, a transistor Q1, a diode D1 and an electrolytic capacitor C1. The invention is suitable for the technical field of maintenance vehicles.
