Abstract

See full text

To provide an electric vehicle capable of reducing heat generation of the switching elements while achieving energy saving, the electric vehicle includes: an engine 11; a first generator 12 driven by the engine; a first rectifier circuit 14 connected to the output of the first generator; a first DC line 16 to receive the DC output of the first rectifier circuit; a driving motor 10 connected to the first DC line; a power converter 20 configured to convert voltage of the first DC line; a second DC line 34 to receive the DC output subjected to voltage conversion by the power converter; an auxiliary device 33 connected to the second DC line; and a controller 40 configured to control the power converter. The controller is configured to, in response to the voltage Vi of the first DC line becoming equal to or less than a first threshold Vc, control the output power Po of the power converter to a rated power P1, and in response to the voltage becoming larger than the first threshold, control the output power Po to be smaller than the rated power.
