ABSTRACT

Abstract: This paper introduces the use of the voltage multiplier technique and passive absorption circuit applied to the non-isolated dc-dc converter in order to obtain high efficiency and high voltage gain. A passive absorption circuit is inserted in the interleaved flyback converter to transfer the leakage energy to load. The operation principle of the circuit is explained. This paper also deals with MPPT controlled high step up dc-dc converter. The switching element used in the flyback converter is MOSFETs, which is completely on and completely off. This is because MOSFET has high power rating and high switching speed. Moreover, high voltage conversion ratio is achieved. The simulated results are presented with R load.
