Inserting an auxiliary switch to the conventional hard-switch full-bridge topology, a novel soft-switching full-bridge converter is proposed. Instead of the main switches, the auxiliary switch is pulse-width modulated to regulate the output voltage and soft-switching operation of the main switches can be easily achieved over full line and load ranges. Consequently, the reduced switching losses can...
This paper proposes that the typical inductance filter in the grid-connected converter should be substituted by T-filter for the increase of harmonic component in the output current to electrical network due to lower PWM switch frequencies in the grid-connected matrix converter of variable-speed constant-frequency wind power generation system. And it has also analyzed the stability of the grid-connected...
In this paper, a novel interleaving control strategy for DC/DC converters is proposed and applied to a new isolated DC-DC converter configuration with two paralleled half-bridge structure at the primary side and a new rectification method at the secondary side of the transformers, aiming at to optimize the design of transformers and reduce the rectifier diodes voltage stresses. The concept of this...
