    • A boost converter (12) boosts a DC voltage of a DC power supply (B). An inverter (14) converts the output voltage of the boost converter into an AC voltage. An AC motor (M1) is driven by the output voltage of the inverter (14). A control device (30) which controls the boost converter (12) reduces an output voltage instruction value of the boost converter (12) in the case where the rotation speed of the AC motor (M1) is decreased and an absolute value of a variation rate of the rotation speed is not less than a predetermined value. The inverter (14) is controlled in the control mode selected from a plurality of control modes including three modes of a sine wave PWM control mode, an overmodulation PWM control mode and a rectangular wave control mode. The control device (30) of the boost converter reduces the output voltage instruction value of the boost converter (12) only in the case where the control mode of the inverter (14) is the rectangular wave control mode or the overmodulation control mode.
    • 升压转换器(12)升压直流电源(B)的直流电压。 逆变器(14)将升压转换器的输出电压转换成AC电压。 交流电动机(M1)由逆变器(14)的输出电压驱动。 控制升压转换器(12)的控制装置(30)在交流电动机(M1)的转速减小的情况下降低升压转换器(12)的输出电压指令值,并且变化的绝对值 转速的速度不小于预定值。 逆变器(14)被控制在从包括正弦波PWM控制模式,过调制PWM控制模式和矩形波形控制模式的三种模式的多个控制模式中选择的控制模式中。 仅在逆变器(14)的控制模式为矩形波控制模式或过调制控制模式的情况下,升压转换器的控制装置(30)才降低升压转换器(12)的输出电压指令值。

    • A voltage converter, which is placed between a DC power source (B) and a motor (Ml), includes: a voltage sensor (10) and an electric current sensor (11), which senses input and output of electric power to and from the DC power source (B), a buck-boost converter (12) having power control elements, which is placed in a path connecting between power lines (PLl) and (PL2) that establish the connection to the DC power source (B) and the connection to the motor (Ml), respectively; and a controller (30) for controlling the buck-boost converter (12). The controller (30) monitors the change in the regenerated power that is supplied to the DC power source (B), based on the outputs from the voltage sensor (10) and the electric current sensor (11), and, if the amount of change in the regenerated power is greater than a predetermined amount, the controller (30) changes the operation mode of the buck-boost converter (12) from a rapid operation mode to a slow operation mode by- decreasing a value of a feedback again.
