Problem to be Solved: To provide an electric drive vehicle that can be implemented inexpensively with a simple configuration, and includes a long-life power supply circuit of a diesel boost system. Solution: A prime mover 03; a generator 04 driven by the prime mover 03; a power supply circuit 30 that uses a generator voltage VR obtained by rectifying a generator output PR and a trolley voltage VL obtained by rectifying an incoming power PL from a trolley feeder 10 as a driving voltage of a load device 12; and a control means 20 that controls drive of the prime mover 03 and opening and closing of a plurality of switches and the like included in the power supply circuit 30 are included. The power supply circuit 30 is configured by connecting a pair of second rectifying means D1 that rectifies the incoming power from the trolley feeder 10 and a second switch S2 connected in series therewith in parallel with a pair of first rectifying means 05 that rectifies the generator output PR and a first switch S1 connected in series therewith, and connecting a third switch S3 in parallel with the second switch S2.
