    • A circuit switching element is provided that switches a step-up/step-down bidirectional chopper circuit, arranged between a DC bus and a power storage element, to a first chopper circuit or to a second chopper circuit, whose step-up and step-down characteristics are in a complementary relation. The first and second chopper circuits are used together at a time of charge and discharge. Accordingly, an AC motor drive device having mounted therein a power storage system is obtained, in which the power storage system can perform charge and discharge to and from the power storage element, regardless of a bus voltage and can increase energy use efficiency.
    • 提供了一种电路开关元件,其将设置在DC总线和电力存储元件之间的升压/降压双向斩波电路切换到第一斩波电路或第二斩波电路,该第二斩波电路的升压和 下降特征是互补关系的。 第一和第二斩波电路在充放电时一起使用。 因此,获得了其中安装有蓄电系统的交流电动机驱动装置,其中蓄电系统可以与蓄电元件进行充电和放电,而不管总线电压如何,并且可以提高能量使用效率。
