    摘要： A rectifier device according to the present disclosure controls a ratio of a short-circuit and an opening of a semiconductor switch based upon a difference between command information, which is a total of a harmonic current waveform with a fixed value within a limit of a harmonic regulation and a sinusoidal current waveform that is variable according to a DC load connected to the rectifier device, and actual current information. The harmonic current waveform is a sum of sine function groups of odd orders, wherein an amplitude of each odd-order harmonic is set to be substantially equal to an allowable value under the harmonic regulation, and each odd-order harmonic becomes a zero phase when a fundamental wave expressed by a sine function becomes a zero phase. When the variable sinusoidal current value is smaller than a predetermined value, the harmonic current waveform is attenuated in conjunction.

    摘要： A controller (500) for determining a distribution of switching phases among switching elements of a power supply system The power supply system has a plurality of voltage converters, each comprising a switching element and being arranged to convert an input voltage supplied to the voltage converters to a respective output voltage by switching the switching element at a predetermined frequency. The controller (500) comprises a receiver (510) for receiving one or more signals indicative of a respective contribution from each of the voltage converters to a ripple voltage component of an input current of the voltage converters, and a rank determining module (520) configured to rank the voltage converters in order of decreasing contribution to the ripple voltage. The controller (500) further comprises a switching phase offset calculator (530) configured to calculate a respective switching phase offset that is to be applied for the switching element in each of the voltage converters by: (i) calculating respective phase offsets of the two highest ranked voltage converters that would minimise an input voltage ripple caused only by said two highest ranked voltage converters; (ii) calculating a phase offset of the next-highest ranked voltage converter that would minimise an input voltage ripple caused only by said next-highest ranked voltage converter and the voltage converters ranked higher than said next-highest voltage converter; and (iii) repeating step (ii) for each subsequent voltage converter in the ranking. The controller (500) also includes an output signal generator (540) configured to generate one or more output signals defining the calculated switching phase offsets to be applied to the switching of the respective switching elements.

    摘要： Provided is a technique of reducing power capacity required for a charge and discharge circuit. A converter (3) performs full-wave rectification on a single-phase voltage (Vin), thus outputting a rectified voltage (Vrec) across DC power supply lines (LL, LH). An inverter (5) receives the rectified voltage (Vrec) and then supplies a three-phase AC current (Iu, Iv, Iw) to an inductive load (6). Between the DC power supply lines (LL, LH) is connected a charge and discharge circuit (4). The charge and discharge circuit (4) includes a buffer circuit (4a) and a boost circuit (4b). The buffer circuit (4a) includes a series connection between a capacitor (C4) and a switch (Sc). The boost circuit (4b), which may be configured by a boost chopper, includes a switch (SI), a reactor (L4) and a diode (D40). The charge and discharge circuit (4) provides and receives part of pulsations of the power input to the converter (3) between the DC power supply lines (LL, LH).
