This utility model discloses a locomotive-specific single-phase inverter power supply, comprising a housing formed by a base plate, a top cover, and four side plates. A main control board mounting bracket within the housing divides the inner cavity into upper and lower chambers. One end of the lower chamber integrates a toroidal transformer and an inductor assembly, while the other end houses a capacitor assembly and a filter. An air switch and a lamp panel assembly are mounted on the upper chamber above the capacitor assembly. The lamp panel assembly includes an inverted U-shaped bracket and several LED lamp holders mounted on the top surface of the bracket. By dividing the inner cavity of the housing into two parts, the structure is more compact. Placing the toroidal transformer, inductor, filter, and capacitor components in the lower chamber, along with a heat dissipation structure, facilitates heat dissipation. The air switch and lamp panel assembly are placed in the upper chamber, with the lamp panel assembly closely attached to the top cover and extending beyond it for easy observation by the operator.
