The main converter is driven by one gate pulse per half recurring cycle and a voltage produced by each sub-converter at AC terminals thereof is controlled to match a difference between an AC power supply voltage and a voltage produced by the main converter at AC terminals thereof, whereby phase voltages of the power converter are generated as the sums of phase voltages of the individual converters.

摘要： A power converting apparatus includes a first inverter (3) connected to a first DC power supply (1) and a plurality of second inverters (4A, 4B) connected in series to the first DC power supply (1). The plurality of second inverters (4A, 4B) provide compensation to an output voltage of the first inverter (3) by the sum of outputs at which a power balance becomes approximately zero. The power converting apparatus generates output voltage commands (VrefA, VrefB) for the respective second inverters (4A, 4B) upon individually making an adjustment so that DC bus voltages of the second inverters (4A, 4B) become equal to each other depending on whether charging or discharging mode is selected while keeping the sum of the individual output voltage commands (VrefA, VrefB) at a target sum voltage (Vref2).
