摘要： Sampling of a control system that controls an inverter and updating of a command value are prevented from being degraded, even when the resonance of an LC filter is suppressed using a suppressing current. In a block 10a, a current distribution factor generator 11 receives an amplitude Vm of a single-phase AC voltage Vin, an amplitude Im of an input current, a command value Idc* of a DC current Idc, a command value Vc* of a both-end voltage Vc, and a power angular velocity ω, and outputs a current command value Ib*. A resonance suppression controller 15 receives a reactor voltage VL, and outputs a correction value k·VL. A subtractor 17 subtracts the correction value k·VL from the current command value Ib*, and provides the result to a chopper controller 16. The chopper controller 16 outputs a boost duty dl based on a corrected current command value (Ib* - k·VL). A comparator 14 compares the booster ratio dl with a carrier C2, and outputs the result as a control signal SSI.

摘要： In a direct power converter employing a boost chopper, a peak current flowing an inductor of the boost chopper is reduced. When a rectifying duty dr, a discharge duty dc, a voltage between both ends Vc of a capacitor (34), and a rectified voltage Vrec of an AC voltage Vin are introduced, a virtual DC link voltage Vdc in an inverter (6) is expressed by dc•Vc+dr•Vrec. The discharge duty dc is a time ratio of continuity of a switch (41). The rectifying duty dr has a value obtained by subtracting the discharge duty dc and a zero voltage duty dz from 1. The zero voltage duty dz is a time ratio for the inverter (6) to adopt a zero voltage vector regardless of a magnitude of a voltage to be output from the inverter (6). The capacitor (34) is charged in the boost chopper (3) at a part of a period during which the virtual DC link voltage Vdc is larger than the rectified voltage Vrec.
