The invention relates to an electric drive for electric vehicles. A vehicle includes an inverter having first and second half bridges configured to provide multiphase voltage to an electric machine. The vehicle further includes a controller configured to activate a switch of the first half bridge and pulse width modulate a switch of the second half bridge to conduct resonant output on a rail of the inverter to the electric machine such that the multiphase voltage is created for at least a sixth of a cycle of the electric machine. The activation is responsive to a torque command.
本公开提供了“用于电动车辆的电驱动器”。一种车辆,其包括具有第一半桥和第二半桥的逆变器,所述第一半桥和所述第二半桥被配置成向电机提供多相电压。所述车辆还包括控制器,所述控制器被配置成激活所述第一半桥的开关并且对所述第二半桥的开关进行脉冲宽度调制,以将所述逆变器的轨条上的谐振输出传导到所述电机,使得针对所述电机的周期的至少六分之一产生所述多相电压。所述激活是响应于扭矩命令。
