Received Sep 25, 2016 Revised Dec 01, 2016 Accepted Dec 11, 2016 Power electronic interface has reached a new level in the area of hybrid energy integration nowadays. The existence for the concept of hybrid energy integration is truly questionable without a proper power electronic interface. In this paper, a modified dual input DC-DC converter which is capable of incorporating two distinct V-I ...

This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vrms ). The topology integrates a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is coupled to the output directly after the first power processing. With this direct power transfer feature and shari...

Due to the decade of fossil fuels at present renewable energy plays an important role in generating power to meet the load requirements. Power produced from the renewable energy is very low. So chopper circuit is required to boost the voltage level of renewable energy sources. Chopper is a circuit in which fixed DC voltage is converted into variable voltage. There are many types of chopper circ...

A Double input DC to DC converter for low voltage energy sources applications is proposed in this paper. The proposed converter is buck-boost converter which can step up or step down the input voltage according to output voltage required at load end. The converter is able to boost up voltage of energy sources such as solar photovoltaic and wind energy system of relatively low voltage. The conve...

The paper proposes a three phase, two switch buck type converter with high power factor.The key feature of the proposed converter is that a switch in the converter has a lower peak voltage stress than a switch in a conventional threephase, single-switch buck-converter. A switch in the converter sees a line to neutral voltage across it rather than a line to line voltage which is the case for the...

This paper describes a new usage of the dc/dc converter developed by D. I. Sheppard and B. E. Taylor in 1983 for achieving high power factor and output regulation. This converter may be viewed as a cascade of a modified boost stage and a buck stage, with the two stages sharing the same active switch. Two possible operation regimes are described. In the first regime, the converter’s input part, ...

The synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide a low-loss recirculation path for the induct...

in this paper, a novel approach for control of the dc-dc buck converter in high-power and low-voltage applications is proposed. designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. it is clear that in high-power applications, parasitic elements of the converter may become comparable with...

This proposal proposes a DC/DC Buck Boost converter which has been used as a smooth starter for a DC Permanent Magnet Motor. In the existing system the DC/DC Buck Converter is used which provide the output less than the input Signal. Using buck converter it is difficult to increase the value of the input signal. Hence DC/DC BuckBoost Converter used from which it is possible to get both the incr...
