    • A power converting apparatus includes a main inverter having a high-voltage DC power supply that operates at a low frequency employing SiC MOSFETs having a high withstand voltage exceeding 600 V and a sub-inverter having a low-voltage capacitor that operates through high-frequency PWM employing Si MOSFETs having a low withstand voltage. With AC sides of the main inverter and the sub-inverter connected in series, the power converting apparatus outputs AC power having a prescribed voltage waveform by adding voltages individually generated by the main inverter and the sub-inverter. Specifically, the SiC MOSFETs are used only in the main inverter of which devices are required to have a high withstand voltage and the Si MOSFETs are used in the sub-inverter of which devices may have a relatively low withstand voltage, whereby conduction loss is reduced with an inexpensive circuit configuration.
    • 电力转换装置包括:主逆变器,其具有使用高耐受电压超过600V的SiC MOSFET的低频工作的高压直流电源以及具有通过高频工作的低压电容器的副逆变器 PWM采用具有低耐受电压的Si MOSFET。 主逆变器和副逆变器的AC侧串联连接,电力转换装置通过加上由主逆变器和副逆变器分别产生的电压,输出具有规定电压波形的交流电力。 具体来说,SiC MOSFET仅用于需要具有高耐压的器件的主逆变器中,并且在其逆变器中使用Si MOSFET,其中器件可能具有相对低的耐受电压,从而降低了传导损耗 具有廉价的电路配置。
