Review of High Step up Converter with Voltage Multiplier for Photovoltaic System

The utilization of photovoltaic energy becomes an important source of electrical energy with the advancement in power electronic technology. The dc-dc converters is one of inevitable part of renewable energy system, for connecting the PV panel to the grid or AC load through an inverter. MPPT (Maximum Power Point Tracking) maximizes the power production of the PV panel. The advantages of high st...

Novel Isolated High-Step-Up DC-DC Converter With Voltage Lift

A novel two-switch high-step-up isolated converter with voltage lift is proposed in this paper. The proposed isolated converter utilizes a transformer with low turn ratio to achieve high step-up gain. The secondary winding charges two boosting capacitors in parallel as switches during the switch-on period, and two boosting capacitors are discharged in series during switch-off period. Thus, the ...

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...

Design of a non-isolated multi-input converter with soft switching and high step-up voltage gain

Energy is one of the most important factors for the economic growth and development of each country. Most of the energy is consumed in the form of electricity. One of the most important ways to generate electricity is to produce electricity through fossil fuels. However, due to their disadvantages such as limitations and concerns about the environment and increased demand for energy, engineers ...
