This paper presents the development of a high gain Boost converter applied to photovoltaic (PV) system. The converter was designed to be connected directly to the photovoltaic panel and perform the search for the maximum power point (MPPT). The new proposal seeks the MPPT is to connect each panel a converter for a high gain greater accuracy in finding the point of maximum power. The converter w...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

In this paper, a new structure of step-up dc-dc converter by using coupled inductor and active-clamped circuit is proposed. The proposed converter generates high voltage gain in comparison with the conventional dc-dc converters. Duo to using active-clamped circuit in the proposed topology the voltage stress on main switch is reduced. In addition the zero voltage switching (ZVS) in ON-state of m...

In this paper, a multiphase boost converter is proposed to achieve high voltage gain and high power gain. The proposed converter operates in continuous conduction mode (CCM) with soft switching of main and auxiliary devices. The transformer in a conventional converter is replaced by an auxiliary circuit which provides the desired voltage and power levels. The zero voltage switching (ZVS) and ze...

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...

<p class="IEEEAbtract">Different types of power conditioning systems are mostly used with renewable energy systems. As the output solar photovoltaic (PV) is low high voltage converters required. These can be for both standalone and grid tied A gain DC-DC converter proposed which modules to get voltage. This provide a proportional integral derivative (PID) controller maintain coupled modul...
