For a nonisolated high step-up converter, the combination of a boost converter with a series output module is investigated in this paper. As a solution to supplement the insufficient step-up ratio and distribute a voltage stress of a classical boost converter, a sepic-integrated boost (SIB) converter, which provides an additional step-up gain with the help […]
Design and Implementation of a Current-Source Converter for Use in Industry Applications of D-STATCOM-Matlab-Power Electronics-2010
This paper deals with the design and implementation of the power stage of a forced-commutated current-source converter (CSC) for use in industry applications of distribution type static synchronous compensator (D-STATCOM). The power semiconductors are switched at 500 Hz according to the switching patterns generated by selective harmonic elimination method for the elimination of the most […]
A Soft Switching Scheme for Multiphase DC/Pulsating-DC Converter for Three-Phase High-Frequency-Link Pulsewidth Modulation (PWM) Inverter-Matlab-Power Electronics-2010
This paper outlines a switching scheme to improve the energy efficiency for an isolated high-frequency multiphase dc/pulsating-dc converter, which is the front end of a three-phase rectifier-type high-frequency-link inverter.Without using any auxiliary circuit, the proposed switching scheme achieves zero-current or zero-voltage switching for the power switches on the front-end multiphase dc/pulsating-dc converter. Moreover, on the […]
Bridgeless SEPIC Rectifier With Unity Power Factor and Reduced Conduction Losses-Matlab-Power Electronics-2009
In this paper, a new bridgeless single-phase ac–dc converter with an automatic power factor correction (PFC) isproposed. The proposed rectifier is based on the single-ended primary inductance converter (SEPIC) topology and it utilizes a bidirectional switch and two fast diodes. The absence of an input diode bridge and the presence of only one diode in […]
