This paper approaches the interleaved boost converter (IBC) for photovoltaic systems (PVS) with efficiency control. The purpose of this converter is to transfer the low DC PV voltage to a high DC voltage at its output. The low output voltage ripple and especially the low input current ripple (for MPPT) are analyzed, verified and compared to N cell IBCs. To improve the efficiency of the IBC, the control decides how many commutation cells are used, in relation to the actual power. This paper also shows to determine the critical PV current needed to work in continuous conduction mode. Finally, a dual IBC is experimental tested to verify the theoretically approaches.

Renewable energy conversion systems are gaining more attention in recent years. The rapid rise of power generation using renewable energy sources forces to implement a power converter with higher conversion efficiency. To ensure this, DC-DC boost converters are employed to obtain the required boosted voltage level. But this topology results in higher ripple which is unfavorable for PV applications. Hence, this paper evaluates three different topologies of Interleaved Boost Converter which is the parallel connection of boost converters. The topologies analyzed are uncoupled, coupled IBC configuration and IBC with voltage doubler circuit. These converters are designed, simulated, and analyzed their performance has been evaluated based on various parameters. From the results, it is observed that IBC with doubler circuit proves to be the best. The circuit configurations of the various converter topologies are simulated in PSIM. The results are verified and validated.

High Power Interleaved Boost Converter for Photovoltaic Applications
Journal of Power and Energy Engineering, 2018
Interfacing DC sources to load/power grid requires DC converters that produce minimum level of current ripples. This is to limit the losses and hence increase the life span of these sources. This article proposes a simple interleaved boost converter that interfaces PhotoVoltaic (PV) module into a common DC-link. The article also addresses the faulty mode operation of the proposed circuit while advising the appropriate remedy actions. A MATLAB and Simulink dynamic platform are used to simulate the transient performance of the proposed converter. The results revealed the effectiveness and the viability of the proposed converter in reducing the ripples in the PV current without employing bulky input inductors or increasing the switching frequency.

Conventional sources like fossil fuels were used earlier to satisfy the energy demands. Nowadays these are being replaced by renewable sources like photo-voltaic sources. Photo-voltaic is a method of generating electrical power by converting the energy from the sun into direct current with the use of semiconductor devices that exhibit photovoltaic effect. They do not cause environmental pollution and do not require any moving parts. Different types of DC-DC Converters have been proposed in literature but Inter-leaved boost Converter (IBC) is widely used because of its fast dynamic response and high power density. This paper presents an analysis of the Ripple Cancellation Network (RCN) based two phase Interleaved boost Converter (IBC) for photo-voltaic applications. The results illustrate that IBC is more efficient than conventional boost converter as it reduces the input current ripple, output voltage ripple, component size and improves its transient response. On adding the Ripple Cancellation Network to the conventional IBC, the output voltage and input current ripple are further reduced without increasing the diode current stress. Simulations are carried out using MATLAB/Simulink software to verify with the theoretical results. Experimental setup is developed for the proposed converter and the results are verified.

On adding the Ripple Cancellation Network to the conventional IBC, the output voltage and input current ripple are further reduced without increasing the diode current stress. Adopting the closed loop voltage mode control, the ripple components are found to decrease significantly at the output thereby achieving a higher level of efficiency. A comparison is drawn between open and closed loop voltage control ripple component values. Simulations are carried out using MATLAB/SIMULINK software to verify with the theoretical results.
In this paper a new interleaved boost converter (IBC) for photovoltaic (PV) power-generation system is proposed. In power-generation systems efficiency and cost are vital criteria which should be taken into consideration .with the proposed converter voltage stress related to one of the switches in IBC decreased noticeably. Furthermore the switching losses is lower than conventional IBC due to softer switching. These advantages lead the photovoltaic system to higher efficiency and lower cost of converter and allow the proposed converter operate in higher switching frequencies. The idea is based on implementation of coupling capacitor in IBC like Zeta and Sepic converters. A 0.5Kw converter is designed and connected to 240W solar cell. The Maximum Power Point Tracking (MPPT) method based on Perturb and Observe (P&O) is used to track efficient power points according to solar irradiation. The Simulation results verify effectiveness of proposed converter.
