In this paper a three-level single-stage power-factor-corrected ac/dc converter is presented. The proposed circuit integrates the operation of the boost power factor correction and the three-level dc/dc converter, and mitigates the drawbacks found in previously proposed two-level single-stage voltage-fed converters. In the paper, the operation of the new converter is explained in detail, its steady-state...
Bi-directional DC-DC converters facilitate controlled flow of energy in both directions. They are useful in battery charging/discharging, UPS, grid-connected renewable energy storage etc. Considerable amount of ongoing research deals with various improvements of these types of converters. This paper presents the optimized design methodology of an isolated bi-directional hybrid full-bridge converter.
An AC-DC single stage voltage-fed PWM full-bridge converter is proposed in the paper. The converter can simultaneously perform input power factor correction and DC-DC conversion using conventional phase-shift PWM and can maintain a primary side DC bus voltage of less than 450 V even at a high input line voltage of 265 V. This is a combination of features that few if any other converters of the same...
The paper introduces a DC-DC multiple converter based on push-pull forward topology and analyzes its operation principle in detail. It has some superiority in low voltage and high current situation. Then the design procedure of the power stage and control circuit is introduced. Finally 5 kW experimental equipment is accomplished
