PROBLEM TO BE SOLVED: To provide a single-phase voltage type AC-DC conversion device that enables such an autonomous parallel operation that an individual device autonomously controls an output deviation even in the case that a plurality of devices are connected in parallel to perform a parallel operation by a single-phase AC, and that can independently control an active power and a reactive power respectively.SOLUTION: A single-phase AC having a predetermined phase difference from a phase of a single-phase AC voltage of an AC terminal is generated, and the generated single-phase AC and the single-phase AC voltage of the AC terminal are utilized to perform PWM control of an inverter. In addition, an active power and a reactive power of the AC terminal are measured, and a single-phase voltage type AC-DC conversion circuit is controlled so as to obtain the desired active power and reactive power. |
