An isolated switched high step up boost DC-DC converter is discussed in this paper. The main objective of this paper is to step up low voltage to very high voltage. This paper mainly initiates at boosting a 30V DC into 240V DC. The discussed converter benefits from the continuous input current. Usually, step-up DC-DC converters are suitable for input whose voltage level is very low. The circuit...

A novel approach is proposed for a high step-up and high efficiency converters with a low switch stress. The integrated boost-flyback converter uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The proposed circuit topology improving highgain ratio, increasing efficiency, reducing the secondary side of c...

This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

A high step-up integrated coupled inductor-capacitor DC-DC converter for renewable energy applications has been proposed in this paper. Because of relative low output voltage systems, a is necessary. In paper, new configuration given by integrating to get the desire gain. The gain dramatically boosted up using inductor charge capacitor and across switch are clamped inherently. possesses only si...
