Abstract
Owing to the low voltage level that renewable energy sources like solar panels frequently provide, and limited capability of simple boost converter, need for high gain step-up dc-to-dc converters are increased. In this article a single switch high step-up dc-to-dc topology with high efficiency is developed. To obtain high voltage gain, the described step-up dc-to-dc topology employs three windings coupled inductor and voltage multiplier cell method. To get the high voltage gain, this innovative converter does not require to work at a high duty cycle state by increasing the turns ratio of the coupled inductor. The suggested converter's working modes and theoretical model are investigated, and finally, a prototype setup is used to verify the theoretical and simulation analyses' correctness.
