Abstract

AC supply is available in different frequencies so many problems occur in different etiquettes; like battery charging needs the nonstop DC supply.  Because of switching losses(AC to DC converters) are befalls in the converters. A new soft switching boost converter with an aux­iliary or secondary switch and resonant circuit is projected in this work. The resonant circuit is consisted of a resonant inductor Lr, two resonant capacitors Cr1 Cr2, two diodes and an auxiliary switch. This combination of elements makes partial resonant path for main switch perform soft switching at zero voltage. The main ad­vantage of this converter topology is that the auxiliary switch also achieves soft switching by help of resonant circuit. The proposed soft switching boost converter can be applied to various fields such as, HVDC converter station, photovoltaic system, power factor correction, electrical vehicles and so forth. To evaluate the authentication of the circuit MATLAB software can be used to simulate and achieve the real time data.   Keywords: Boost converter, auxiliary resonant converter, ZCS, ZVS, MATLAB Cite this Article Kumar N, Jain R, Tripathi A.

    AC supply is available in different frequencies so the many problems are occurs in different etiquettes like battery charging needs the nonstop DC supply. AC to DC converters wants for some requests. Because of switching losses are befalls in the converters. A new soft switching boost converter with an aux­iliary or secondary switch and resonant circuit is projected in this work. The resonant circuit is consisted of a resonant inductor Lr, two resonant capacitors Cr1 Cr2, two diodes and an auxiliary switch.
