摘要： A power conversion device includes a converter (1) which converts AC power supplied from an AC power source (e1) into DC power, a DC reactor (3), and an inverter (2) which converts the DC power provided from the converter (1) through the DC reactor (3) into AC power and supplies the AC power to a load. A control unit (20) controls the converter (1) according to a sum of a feedback control amount and a feedforward control amount, the feedback control amount being calculated based on a deviation between a current command value and the DC current flowing into the DC reactor (3), the feedforward control amount being set in accordance with a DC voltage provided from the converter (1) through the DC reactor (3). When an output frequency of the inverter (2) is in a first region, the control unit (20) reduces a control gain used to calculate the feedforward control amount, as compared to when the output frequency is in a second region having a frequency lower than that of the first region.

摘要： The present invention provides a parallel current-sharing device and control method without a current-sharing bus, for implementing parallel current sharing of direct-current outputs of a plurality of power conversion submodules. The parallel current-sharing device comprises a voltage control module and a plurality of power conversion submodules. The voltage control module and the plurality of power conversion submodules having parallel outputs form an outer voltage loop. The power conversion submodules comprise respective inner current loops and sample respective current feedback signals to generate inner current loop control signals, and the inner current loop control signals are superposed with an outer voltage loop control signal to control output of the power conversion submodules. An independent current bus is not required, and only one unidirectional outer control voltage loop is required. Functions the same as those of a conventional device are realized; the design, production and debugging of circuits of the parallel current-sharing device are simpler; a rapid multi-parallel dynamic response is realized; a ground wire loop current is eliminated, improving the anti-interference capability of the device; and multi-module parallel current sharing of a switching power supply or a linear power supply under analog control or digital control is realized very easily.
