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...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

This paper presents a comparative analysis of DC-DC Converters for Renewable Energy System. It has been proved that DC-DC converter with transformer is suitable for Electrolyser application. Due to high input and output voltage differences, the topologies with a high frequency voltage matching transformer are analyzed. The comparative analysis is done with and without Transformer topology in or...

Boost half bridge DC-DC converters in the combination of an input-series and output-series (ISOS) connected configuration with a stable control strategy has been investigated in this paper. A stable control strategy comprises of two loops that are current loop and voltage loop. The reference to the current loop has been chosen from the input side of the DC-DC converter. The reference to the vol...

Boost-type dc-dc converters present non-minimum phase dynamic system characteristics. Therefore, controller design using only the output voltage for feedback purposes is not a very straightforward task. Even though control can be achieved inductor current control, implementation of such current-mode controllers may require prior knowledge load resistance and also demand more states as one or cu...

This paper presents a discrete-time output feedback controller to regulate the voltage of DC-DC buck converter.

First, document exposes theoretical analysis closed-loop system, where it considered problem implementing real-time differentiator with good relationship between exactness and noise filtration...

This paper presents novel concept of a multiple converter. It works in three modesAC-AC converter voltage regulator, AC-AC converter frequency changer and AC-DC converter. All three modes work simultaneously. AC-AC converter mode of operation alters low input frequency to high output frequency across the load. AC-DC converter mode of operates with variable amplitude across load. This concept is...
