This paper presents implementations of a nonisolated, high voltage gain DC-DC converter. High voltage gain is achieved due to inclusion of resonance and transformer in the circuit. The performance of this converter is compared with two similar topologies namely coupled inductor-switched capacitor step-up converter and coupled inductor step-up converter. The proposed prototype is designed using ...

The KY Converter, Which is a step up converter, The name given to this converter is first letter of the authors, K.I. Hwu, Y. T. Yau. This converter always operate in CCM, and the output current is non-pulsating, and low output voltage ripple and higher voltage boosting capability. In this paper, different modes of KY Converters are studied. The simulation is carried out to study the perfomance...

This paper presents a novel high-efficiency three-port bidirectional DC–DC converter for photovoltaic (PV) systems. A PV system’s output is stepped up to supply DC bus or load while charging the battery. When insufficient, battery voltage bus; when has excess energy, it down charge Thus, step-up/step-down achieved. common-core coupled inductor was designed and adopted in proposed converter. Pow...

In this article our objective is to obtain steady state characteristics of shunt, series, and separately excited DC motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. We assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. It is ...

This paper presents an analysis of a three-phase rectifier with high power factor using a Sepic DC-DC converter operating in continuous conduction mode (CCM). The structure is particularly simple and robust. Its main features are: one power processing stage, which can operate as step-down or step-up voltage, lower harmonic distortion in the line current and natural isolation. The converter work...

This Paper focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches, i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter, only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the swi...
