AC/AC Power Conversion Based on Matrix Converter Topology with Unidirectional Switches
نویسندگان
چکیده
In this paper, a new type of ac/ac converter is proposed. The proposed converter is capable of direct ac/ac power conversion and, except for a few small snubber elements, it does not require the use of any input inductors or a dc-link capacitor. In contrast to the matrix converter, which requires bidirectional switches, the proposed converter consists of only unidirectional switches such as insulated gate bipolar transistors. The converter has a unity input displacement power factor, and its input line current waveform is similar to that of a diode rectifier with a dc-link inductor. The proposed converter has been validated experimentally using an induction motor driven with field-oriented control.

Design and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
