    • An inverter and a control unit that has a command signal processing unit and a PWM frequency control unit and performs pulse width modulation control are provided. If the command signal processing unit has received a first PWM frequency command signal, it outputs a low PWM frequency command signal so that synchronous or asynchronous PWM control is performed at a PWM frequency in a predetermined frequency range. The command signal processing unit outputs a high PWM frequency command signal so that synchronous or asynchronous PWM control is performed at a higher frequency than the above-mentioned frequency if the command signal processing unit has received a second PWM frequency command signal and until a predetermined time period elapses. The command signal processing unit outputs a low PWM frequency command signal if it has received the second PWM frequency command signal and after the predetermined time period elapsed.
    • 提供了具有命令信号处理单元和PWM频率控制单元并执行脉宽调制控制的逆变器和控制单元。 如果命令信号处理单元已经接收到第一PWM频率命令信号,则其输出低PWM频率命令信号,使得以预定频率范围中的PWM频率执行同步或异步PWM控制。 命令信号处理单元输出高PWM频率命令信号,使得如果命令信号处理单元已经接收到第二PWM频率命令信号并且直到预定时间为止,则以比上述频率更高的频率执行同步或异步PWM控制 期限过去了。 如果命令信号处理单元已经接收到第二PWM频率命令信号并且在经过预定时间段之后,则命令信号处理单元输出低PWM频率命令信号。
