Simulation and modeling Of SEPIC converter with high static gain for renewable application

Single-ended primary-inductor converter (SEPIC) is a dc-dc converter which uses a series capacitor to couple energy from the input to the output. The customized SEPIC converter by two configurations lacking magnetic coupling and by means of magnetic coupling is presented with two high-static gain here. The configuration through magnetic coupling have an output voltage of efficiency 91.9% with a increase in constant gain and maintains a low switch voltage. The configuration lacking magnetic coupling works with an effectiveness of 92.2% by utilizing the properties of SEPIC converter as it has a minimal active component with low blare operation. The advantage of presented topology is low switching voltage and high effectiveness for low input voltage and tall output voltage application.
