The invention provides a high-power helicopter starting direct-current power supply vehicle which comprises a three-phase input power distribution circuit, a three-phase PWM rectifier module, a high-voltage filter capacitor, a DC-DC module and a control module. The three-phase input power distribution circuit is connected with the three-phase PWM rectifier module, the three-phase PWM rectifier module is connected with the DC-DC module through the high-voltage filter capacitor, and the DC-DC module comprises two H-bridge IGBT modules and six transformation rectifier modules; the two H-bridge IGBT modules are connected in an interleaving parallel phase-shifted full-bridge wave-by-wave current-limiting control mode, and each group of three transformation rectification modules adopts a primary series connection and secondary parallel connection structure; the control module is connected with the three-phase PWM rectifier module and the two H-bridge IGBT modules, and is used for controlling the three-phase PWM rectifier module and the two H-bridge IGBT modules to carry out DC voltage conversion and supply power to the helicopter. The power supply power requirement of the helicopter is met, and harmonic pollution to an input power supply is reduced.
