High Efficiency Two Port SEPIC Converter For Hybrid Charging Station

This paper focuses on a Single-Input Dual-Output SEPIC converter, a design that offers substantial benefits. The SEPIC converter offers a notable advantage in achieving substantial voltage gain without necessitating excessively high duty cycles or the use of a transformer. This feature leads to reduced voltage stress in comparison to other buck-boost converters, making it particularly advantageous for sustainable energy sources. Furthermore, the voltage amplification can be further expanded by incorporating a diode and capacitor within the fundamental SEPIC topology, commonly referred as the single level configuration. The converter operates at a switching frequency of 20 kHz and aims to produce dual output voltages as its primary objective.
