In this paper, analysis, design and implementation of non-isolated soft-switching bidirectional DCDC converter with an active switch are described. The proposed topology gives the output voltage as twice as the input voltage and enhances the efficiency up to 94.5% and 92.9% for boost and buck mode operation by proper selection of the duty cycle. Soft switching can be achieved at both steps up a...

This paper presents the intelligent charging and discharging management method for the solar power management circuitry based on fuzzy logic control theory. The mathematical model of DCDC circuit is established, and through Matlab theoretical derivation the feasibility of the maximum power point tracking by the method of obtaining the maximum output current through control is proven. And the ex...

Zero-current (ZC) switching pulse-widthmodulated (PWM) flyback DC-DC converter is an extended version of the single switch flyback converter with an additional active circuit. The purpose of the active circuit is to turn-off the main switch with zero-current switching (ZCS) condition to reduce the turn-off switching loss. This paper presents an overview of the ZCS flyback PWM DCDC converters. T...

In this paper, a comparative analysis on the bifurcative and chaotic behaviour of a current controlled buckboost converter with soft switching and hard switching is performed. The electromagnetic interference generated during hard switching and soft switching of the converter is analyzed. Simulation and measured results show that the total energy is more evenly spread over the frequency band du...

The Conventional Boost Converters is not possible to obtain the high voltage gain. In this paper a DCDC boost converter is proposed for achieving high voltage gain and to reduce the harmonic content in the output side. The circuit diagram of the proposed converter is consists of coupled inductor. Therefore the voltage stress on the active switch is reduced due to the presence of the inductor an...

<p>Photovoltaic (PV) systems can be made more efficient by forcing the PV panel to operate at its maximum point power due electrical properties of photovoltaic generators, which are substantially non-linear (MPP). This study examines effectiveness using a combination parabolic concentrator Bi-reflector and heat exchanger as cooling system on performance generators get photovoltaic/thermal...

DC-DC converters are widely used as reliable power source for many industrial and military applications, computers and electronic devices. Several control methods were developed for DCDC converters control mostly with asymptotic convergence. Synergetic control (SC) is a proven robust control approach and will be used here in a so called terminal scheme to achieve finite time convergence. Lyapou...

This paper presents the design of simple but powerful soft switching scheme for a DCDC Boost Converter with a closed loop control. A new novel soft switching scheme is proposed with a single switch and minimum components which offers load independent operations. The only switch used in this converter is switched ON at zero current and switched OFF at zero voltage .The proposed Controller is use...
