发明名称 ELECTRIC VEHICLE
摘要 An electric vehicle including: an induction motor generator; a synchronous motor generator; an inverter that converts a supplied high voltage VH to an AC voltage to be supplied to the induction motor generator and the synchronous motor generator; and a control unit that adjusts the rotational speed and torque output of the induction motor generator and the synchronous motor generator, wherein the control unit includes a voltage oscillation reduction program for causing the induction motor generator to generate voltage oscillation in a phase opposite to voltage oscillation of the high voltage VH to reduce the voltage oscillation of the high voltage VH when the high voltage VH supplied to the inverter oscillates at an amplitude equal to or greater than a predetermined voltage value due to rotation of the synchronous motor generator. As a result, the voltage oscillation in a PCU of the electric vehicle is reduced.

主权项 1. An electric vehicle comprising: at least one induction motor for driving a vehicle; at least one other motor for driving a vehicle; at least one inverter that supplies at least one AC voltage to the at least one induction motor for driving a vehicle; at least one other inverter that supplies at least one other AC voltage to the at least one other motor for driving a vehicle; and a control unit that adjusts respective rotational speed and respective torque output of each of the at least one induction motor for driving a vehicle and the at least one other motor for driving a vehicle, wherein the control unit comprises voltage oscillation reduction means for causing the at least one induction motor for driving a vehicle to generate voltage oscillation in a phase opposite to voltage oscillation of DC voltage to reduce the voltage oscillation of the DC voltage when the DC voltage supplied to the inverters oscillates at an amplitude equal to or greater than a predetermined voltage value due to rotation of the at least one other motor for driving a vehicle.
