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...

Modeling Approaches for DC-DC Converters With Switched Capacitors

In this paper we review relevant problems in the modelling of DC-DC converters with switched capacitors. We study several approaches that overcome the exposed modelling difficulties, addressing ideal and nonideal cases and using dynamic equations that are valid in a large signal domain.

A New Topology for Z-Source Inverter Based on Switched-Inductor and Boost Z-Source Inverter

In this paper, a new topology for boost Z-source inverterbased on switched-inductor cell is proposed. The operating modes of the proposed inverter are analyzed and also a suitable control method to generate the trigger signals of the inverter is presented. Having a common earth between the input source and inverter and capability to generate a higher voltage gain by using lower amounts of the d...
