摘要： Provided is a method for controlling operation of semiconductor gates in a power conversion system including one or more multilevel inverters coupleable to a modulator and a controller. The method includes generating, via the controller, a control signal responsive to an output current power factor associated with the inverters and producing a discontinuous pulse width modulation reference signal based upon the control signal and a target output power, the discontinuous pulse width modulation reference signal being indicative of shifting a phase angle between current and voltage. A gating signal is generated for output from the modulator, as a function of the reference signal and a carrier waveform. The gating signal adjusts the phase angle to prevent switching of the semiconductor gates.

摘要： A resonant induction wireless power transmission apparatus having intrinsic line power factor correction provides a method of wireless transmission with a near unity power factor, low harmonic distortion load at the line connection point without employing specific power factor correction circuitry. The apparatus provides a transmission frequency inverter operated with a rectified sinusoidal supply voltage instead of a conventional direct current voltage. The resonant induction transfer coil pair is transformed into an impedance inverter by addition of two series connected resonating capacitors of specific value. The impedance inverter raises the secondary side voltage under conditions of light loading and in this way forces line frequency source current and secondary side load current to be proportional, thereby maintaining near unity line load power factor and low harmonic current distortion.

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).

摘要： The present invention discloses a power conversion apparatus and a method for configuring the same. The power conversion apparatus includes a boost unit and at least two power conversion units; each of the power conversion units has two input ends; an input end of the boost unit is connected with one end of an alternating-current power supply, and an output end of the boost unit is connected with one input end of a first power conversion unit of the plurality of power conversion units; one input end of a last power conversion unit of the plurality of power conversion units is connected with the other end of the alternating-current power supply; and the input ends of the plurality of power conversion units are connected in series, and the output ends of the plurality of power conversion units are connected in parallel. Thus, a voltage stress and a current stress on a switching device is 1/n times those of the existing power conversion apparatus, so that switching and conduction losses are reduced, and under the same ripple condition, an input inductance of a PFC unit is significantly reduced, thereby reducing a volume of an inductor and increasing power density.
