    • Provided is a technology capable of ensuring drivability of an electric vehicle while preventing thermal destruction of its parts and deterioration of a battery, caused by an LC resonance. The present specification discloses a motor controller for an electric vehicle having a battery, a converter circuit, an inverter circuit, a smoothing capacitor, and a motor, the motor controller configured to control a drive of the motor by controlling an operation of the inverter circuit. In this motor controller, an operating region of the motor that causes a resonance of an LC circuit configured by a reactor of the converter circuit and the smoothing capacitor is set as a resonance region. In this motor controller, execution of square-wave control on the motor is permitted only over a predetermined time period, when the converter circuit is not boosting the DC power and an operating point of the motor is included in the resonance region.
    • 提供了一种能够确保电动车辆的驾驶性能同时防止其部件的热破坏和由LC共振引起的电池劣化的技术。 本说明书公开了一种具有电池,转换器电路,逆变器电路,平滑电容器和电动机的电动车辆的电动机控制器,所述电动机控制器被配置为通过控制所述逆变器电路的操作来控制所述电动机的驱动 。 在该电动机控制器中,将由转换器电路的电抗器构成的LC电路和平滑电容器共振的电动机的动作区域设定为共振区域。 在该电动机控制器中,只有在转换器电路不升压直流电力并且电动机的工作点被包括在谐振区域中时,才允许在预定时间段内对电动机执行方波控制。
