<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...

This paper proposes a high voltage gain dc/dc converter with coupled inductor cells and switched capacitor for renewable energy applications. It includes coupled inductor, switched capacitor and voltage multiplier cell. Switched capacitor charged during off period by using the energy stored in the coupled inductor. This will increase the performance of the converter. The voltage gain of traditi...

To provide a high votage conversion ratio, conventional non-isolated DC-DC boost topologies, which have reduced voltage capability, to operate with extremely duty cycle higher than 0.9. This paper proposes converter is mainly based on the narrow range of ratio achieve extra gain at relatively stress semiconductors. In addition, it does include any magnetic coupling structure. The structure prop...

High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

A high gain nonisolated DC-DC converter using a single power semiconductor switch is proposed in this article. The operation of the explained under continuous conduction mode (CCM), discontinuous (DCM), and boundary (BCM). mathematical expressions for steady-state voltage gain, stress, current stress diodes are provided. Also, design inductors capacitors CCM with appropriate equations. topology...
