A novel approach is proposed for a high step-up and high efficiency converter 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 high-gain ratio, increasing efficiency, reducing the secondary side of c...

A topological review of the single stage power factor correctted (PFC) rectifiers is presented in this paper. Most of reported single-stage PFC rectifiers cascade a boosttype converter with a forward or a flyback dc-dc converter so that input current shaping, isolation, and fast output voltage regulation are performed in one single stage. The cost and performance of a single-stage PFC converter...

For hybrid electric vehicles, the batteries and the drive dc link may be at different voltages. The batteries are at low voltage to obtain higher volumetric efficiencies, and the dc link is at higher voltage to have higher efficiency on the motor side. Therefore, a power interface between the batteries and the drive’s dc link is essential. This power interface should handle power flow from batt...

DC–DC power converters have generated much interest, as they can be used in a wide range of applications. In micro-inverter applications, flyback topologies are relevant research topic due to their efficiency and simplicity. On the other hand, solar photovoltaic (PV) systems one fastest growing most promising renewable energy sources world. A electronic converter (either DC/DC or DC/AC) is need...
