摘要: In a power converting apparatus which converts AC into DC power, an inverter circuit including at least one series-connected single-phase is connected in downstream of stage input rectified series therewith. the circuit, there are provided smoothing capacitor via rectifier diode and short-circuiting switch for bypassing capacitor. The set to ON state only each phase ranges midpoint matches zero-crossing phases output controlled by using current command so that voltage follows target factor improved.
