摘要： A three-phase inverter circuit (4) of which DC portion is smoothing capacitors (3) connected between output terminals of a solar battery (1) and single-phase inverters (5a-5c) connected in series with AC output lines of the three-phase inverter circuit (4) together constitute an inverter section, and this inverter section is connected to a three-phase power system (2). The three-phase inverter circuit (4) outputs a reverse-polarity voltage pulse (10ua) during a period within each of basic voltage pulses of which pulsewidth corresponds to a half cycle every half cycle of a system voltage. A power burden born by the individual single-phase inverters (5a-5c) in each half cycle is made approximately zero and the individual single-phase inverters (5a-5c) make a correction for subtracting a common voltage (Vo) from target output voltages of individual phases during the period when the reverse-polarity voltage pulse (10ua) is generated.

摘要： A power supply system (1) is a DC power supply and distribution system that converts AC power received from a main power source (2) into DC power and supplies the DC power to a load (3). The power supply system (1) includes a power converter (10), a load state detector (20), and a controller (30). The power converter (10) converts AC power received from the main power source (2) into DC power with a voltage in accordance with a distribution voltage command value Vref and supplies the DC power to the load (3). The load state detector (20) detects an operating state of the load (3). The controller (30) operates in an operation mode selected from among a plurality of operation modes and generates the distribution voltage command value Vref. The operation modes include a distribution voltage control mode in which the distribution voltage command value Vref is generated based on load operating information detected by the load state detector (20) and a distribution voltage fixed mode in which a predetermined setting value or an external command value acquired from an external device (4) is set as the distribution voltage command value Vref.
