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： Using two converters (1, 2) placed in a primary-side and a secondary-side and each configured as a single-phase full-bridge, and one single-phase transformer TR, a power conversion device converts DC power of a primary-side capacitor to which a primary-side DC voltage is applied, to DC power of a secondary-side capacitor to which a secondary-side DC voltage is applied, through a transformer (1, 2). A control device (10) sets a dead time Td1 for the converter (1) serving as a power-transferring side converter, to be equal to or less than a current-polarity reversal time Tcmtt, to thereby surely achieve zero-voltage switching.
