A Front end of the Photovoltaic Solar Panel is been proposed based on Step-Up Converter. The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations. The specification of a power electronic interface is subject to requirements related not only to the renewable energy source itself but also to its effects on the power-system operation, especially where the intermittent energy source constitutes a

Implementing a voltage multiplier module, an asymmetrical interleaved high step-up converter obtains high step-up gain without operating at an extreme duty ratio. The voltage multiplier module is composed of a conventional boost converter and coupled inductors. An extra conventional boost converter is integrated into the first phase to achieve a considerably higher voltage conversion ratio. The two-phase configuration not only reduces the current stress through each power switch, but also constrains the input current ripple, which decreases the conduction losses of metal-oxide-semiconductor field-effect transistors. In addition, the proposed converter functions as an active clamp circuit, which alleviates large voltage spikes across the power switches. Finally, the simulation circuitry with a 40V input voltage and 230V output voltage is operated to verify its performance analysis with respect to the Fuzzy Logic Controller. The highest efficiency is 97.75%.
