High-Step-Up DC-DC Converter using Three-Winding Transformer and Soft-Switching for use in Photovoltaic Systems

In Photo Voltaic system, this idea of converter can be used to increase efficiency. For increase of voltage gain advantage, advised architecture accommodates a lift converter with proper coupled inductors. It has benefits like continuous input current, high amount of efficiency, three-winding coupled inductors generally used to increase the amount of voltage gain, there is a method called soft switching is being used for the sake of decrease losses in the diode and to decrease the voltage stress at switch and also helps in creating the absence of problem of reverse recovery diodes. There are many research actions going on among them, these coupled-inductor boost converter already got a lot of priority, and they are known to be the best option for the case of high step-up applications. There is only one switch is being used in this converter and this switch is basically controlled under the condition called Zero Current Switching (ZCS), as it contains diodes. The percentage of voltage stain at the point of transfer is generally less than the voltage at the output. So, builds up conversion performance above 95%.
