Controlled Single Switch Step down AC/DC Converter without Transformer

This paper presents a transformer less ac/dc converter which can be used in voltages between 90230 Vrms. Instead of a transformer, this topology consists of a buck dc/dc converter and a buck boost dc/dc converter. By the absence of transformer, reduce the complexity of converter and it is cost effective. Buck dc/dc converter keeps o/p voltage below the line voltage; limit the leakage current. B...

Design and analysis of contactless transformer using series resonant converter

A loosely contactless transformer with a large air gap has small magnetizing inductance and large leakage inductance comparing with a closely conventional transformer. This paper focus on analysis, design and measurement results of the loosely winding contactless transformer using resonant converter. Finally, the experimental set up is built to transfer power of 300 W over the different gap var...

Novel Resonant Converter Topology Realized by Adjusting Transformer Parameters

This paper shows a new direction as to how the transformer parameters may be best utilized and presents the performance and control of novel DC/DC and AC/DC converter topologies. All the three inductances of a transformer have been utilized to realize a CL topology having excellent characteristics and requiring no external inductor. For half bridge topology the capacitor used for the purpose of...

Hybrid Z-Source DC-DC Converter with ZVZCS and Power Transformer Resetting: Design, Modeling, and Fabrication

This paper introduces a novel two transistors forward topology employing a z-source to achieve ZVZCS and power transformer resetting for various applications. Comparing with the forward converter, this topology has the advantage of displaying ZCS condition with an added Z-Source and no additional switches when the switches turn on, and that ZVS condition happens when the switches turn off. Duty...
