Boost-flyback Converter With Voltage Multiplier Cells For Alternative Energy Applications

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...

Active Clamp Zvs Flyback Converter with Output Voltage Douler

Power Factor Correction (Boost PFC Converter with Two-Switch Clamped Flyback Converter)

The devices such as diode and thyristor are generally used in industrial, commercial and residential applications hence need to undergo rectification for their proper functioning and operation. They are connected to the grid comprising of non-linear loads and thus have non-linear input characteristics, which results in production of non-sinusoidal line current. Due to the increasing demand of t...

Zero Voltage Switching of Two-switch Flyback- Forward Converter

FORWARD CONVERTER Jhao-Cyuan Huang, Yong-seng Wong, Kuo-Bin Liu, NSRRC, Hsinchu, Taiwan Abstract The traditional pulse-width-modulated flyback converter power switch has serious electromagnetic interference (EMI) and lower conversion efficiencies problems due to the hard-switching operations. This paper produces a zero voltage switching of flyback-forward converter with an active-clamp circuit,...

Cascaded Boost Converter for PV Applications

Among renewable energy sources, solar power has the potential to become one of the main contributors to the future electricity supply. Low voltage photovoltaic systems require a high voltage gain converter for module’s grid connection through a DC-AC inverter. This paper proposes a converter that achieves a high step-up voltage conversion ratio, which contains a coupled inductor, without extrem...
