    • PROBLEM TO BE SOLVED: To provide a motor drive device which receives power provided from a DC power source and can reduce ripples contained in a current flowing in the DC power source during execution of single pulse control.SOLUTION: A motor drive device 1 comprises: an inverter 2 which converts DC power inputted via a DC bus from a DC power source 3 into three-phase AC power to output it to an IPM motor 8; an inverter control device 10 having a single pulse control mode that, during a single cycle of an electrical angle, applies a square wave voltage of single positive and negative pulses to switching elements corresponding to each phase, as a gate drive signal. The inverter control device 10, in a case where the single pulse control mode is executed, causes the duty to gradually increase or decrease at a prescribed phase angle width when a square wave voltage rises and falls.
    • 要解决的问题:提供一种电机驱动装置,其接收从直流电源提供的电力,并且可以在执行单脉冲控制期间减少在直流电源中流动的电流中包含的波纹。 电动机驱动装置1包括:逆变器2,其将通过DC总线输入的直流电力从直流电源3转换为三相交流电力,将其输出到IPM电动机8; 具有单个脉冲控制模式的逆变器控制装置10,其作为栅极驱动信号,在电角度的单个周期期间,将与每个相位对应的开关元件施加单个正和负脉冲的方波电压。 逆变器控制装置10在执行单脉冲控制模式的情况下,当方波电压升高时,使占空比以规定的相位角宽度逐渐增大或减小。 版权所有(C)2013,JPO&INPIT
