Operation Modes of a Secondary-Side Phase-Shifted Resonant Converter

Abstract: In this work, a unidirectional full-bridge resonant converter with secondary-side phase-shifted control is addressed. With the variation of voltage gain and power level, this converter may enter into different operational modes, including three continuous current modes and one discontinuous current mode. The details in each operation mode are discussed one by one. The boundary conditi...

Simulation and Experimental Verification of Closed Loop Operation of Buck / Boost DC-DC Converter with Soft Switching

A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

Operation of Three-Phase Resonant Converter in Single- Phase AC-to-DC Applications

A single-phase ac-to-dc converter using threephase modified series-parallel resonant converter is proposed in this paper. The three-phase resonant converter is analyzed using Fourier series approach. The design curves for a resonant converter of 2.5 kW rating are plotted. The converter components are selected based on the design curves. The converter is simulated for different load conditions u...

Parallel Operation of Hybrid Loaded Resonant Converter Using Phase-Shift Control

This paper presents a phase shifting method to adjust the combined output voltage of two Hybrid Loaded Resonant Converters connected in parallel. The method implements a fixed switching frequency and hence it is particularly useful in applications such as medical instrumentation where audible noise is not desirable. The design and analysis of parallel Hybrid Resonant Converters operating in dis...
