“…Conventional boost converter has a simple circuit and low cost [8]. The disadvantages of conventional boost converter are high ripple current on active and passive components, large voltage stress for power switches, and require a large capacitor value to keep the output voltage steady [9]. This difficulty can be solved by using interleaved boost converter which is another power boost converter circuit [10].…”

DC-DC boost power converters play an important role in solar power systems; they step up the input voltage of a solar array for a given set of conditions. This paper presents an overview of the variance boost converter topologies. Each boost converter is evaluated on its capability to operate efficient, size, and cost of implementation. Conventional boost converter and interleaved boost converter are widely used topologies in photovoltaic systems reported; however, they have negative sides of varied efficiency level under changed weather conditions. Therefore, this paper proposes, interleaved boost converter with novel switch adaptive control, to maximise efficiency of standalone photovoltaic system under change of solar power levels, due to illadation condition.

“…However, the drawback of this converter is that the voltage across the switch is very high during the resonance mode components [8]. Lee et al [9] described the optimal design of the resonant components and the interleaved method is proposed for resonant current reduction. That the interleaved method distributes the input current to each phase, the current rating of the switching devices can be decreased by using interleaved method.…”

The reliability, efficiency, and controllability of Photo Voltaic power systems can be increased by embedding the components of a Boost Converter. Currently, the converter technology overcomes the main problems of manufacturing cost, efficiency and mass production. Issue to limit the life span of a Photo Voltaic inverter is the huge electrolytic capacitor across the Direct Current bus for energy decoupling. This paper presents a two-phase interleaved boost converter which ensures 180 angle phase shift between the two interleaved converters. The Proportional Integral controller is used to reshape that the controller attempts to minimize the error by adjusting the control inputs and also real coded genetic algorithm is proposed for tuning of controlling parameters of Proportional Integral controller. The real coded genetic algorithm is applied in the Interleaved Boost Converter with Advanced Pulse Width Modulation Techniques for improving the results of efficiency and reduction of ripple current. Simulation results illustrate the improvement of efficiency and the diminution of ripple current.

“…Therefore the degree of ripple cancellation is also varying parameter. The most optimum cancellation of ripple is a function of the duty cycle of the converter and the number of phases [6]. A method of measuring the variation of the ripple cancellation as duty cycle is varied is by using the factor Fc as shown in figure [7], [8].…”

Abstract-In ac/dc power factor correction (PFC) applications, where a wide range dc link voltage is required, boost derived topologies are no longer the most suitable circuit topologies for universal grids. In this paper an interleaved SEPIC converter, capable of providing a wide range dc link voltage is investigated. The interleaved converter is able to process more power with reduced circuit ripples and harmonics distortion, and current stresses. Additionally, because the coupled inductors share a common magnetic core, the count of magnetic devices is kept the same as the single-phase topology. Moreover, using coupled inductors effectively solves the current sharing problems caused by the duty cycle mismatch. The phase of the gate signals among different phases can be artificially shifted by a certain degree which would contribute to reduce the circuit harmonics as well as the current ripples.
