This paper describes a novel hybrid modulation scheme for the operation of an isolated high-frequency and high-power direct-power-conversion (DPC) inverter. It enables: (a) removal of the dc-link filter evident in conventional inverters where the diode rectifier stage is followed by low-pass filter and a voltage-source inverter (VSI); (b) significant reduction in switching loss of the inverter by...
This paper presents a new soft switched topology for losses reduction in a three-phase four-wire shunt active power filter (SAPF). The soft-switching technique not only offers a reduction in switching loss and thermal requirement, but also allows the possibility of high frequency and snubberless operation. Improved circuit performance and efficiency as well as reduction of EMI emission can be achieved...
This paper presents a strategy of matrix converter driving three-phase brushless DC motor (BLDCM) with trapezoidal back electromotive force. The matrix converter is described as an equivalent circuit combining virtual rectifier stage and virtual inverter stage. Input current space vector modulation and 120deg conduction mode are employed in these two stages respectively. An important part of this...
