Abstract
A power converting apparatus includes three sets of half-bridge inverters connected between output terminals of a solar battery, each of the half-bridge inverters including two series-connected switching devices, single-phase inverters connected to individual AC output lines of the bridge inverters, and two series-connected capacitors dividing a voltage of the solar battery, wherein output terminals of the single-phase inverters are connected to individual phases of a three-phase power system. Each of the half-bridge inverters is operated to output one pulse per half cycle, each of the single-phase inverters is controlled by PWM control operation to make up for a voltage insufficiency from the system voltage, and sums of outputs of the half-bridge inverters and the single-phase inverters are output to the power system.
