Abstract:

In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are suitable choice for this purpose. Since the output voltage is high, the series structure can be a good choice.

A Coupled Inductor Based High Voltage Gain DC-DC Converter Using Interleaved Voltage Multiplier Cells

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...

Analysis of New Transformerless dc-dc Converter With High Voltage Gain

In some industries applications such as fuel cells, we must use a high voltage gain dc-dc converters for increasing voltage, but, the conventional converters cannot provide the high voltage gain with increasing duty cycle and the converters efficiency is limited by the equivalent series resistances. For this reason, in this paper, a single switch transformerless high step-up dc-dc converter wit...

Design & Implementation of Soft Switching Dc-dc Converter with High Voltage Gain for High Power Application

A zero voltage switching (ZVS) dc–dc converter with high voltage gain is proposed. It consists of a ZVS boost switch cell converter stage and a ZVS half-bridge converter stage with resonant converter and all these stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS halfbridge converter stage pr...

Design of a 5kW High Output Voltage Series-Parallel Resonant DC-DC Converter

This work presents a comprehensive procedure for designing a high output voltage series-parallel resonant DC-DC converter. The system output voltage control is by a combination of duty-cycle and switching frequency variation, where soft-switching is preserved over the entire operating range. The basic principle of operation of the converter is described and an analytical model is established wh...
