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.

“…The alternating current is turned to direct current by rectifier and the direct current is turned to alternating current in case of inverter. But there were some converters which tends to improve the voltage gain with in the direct current like boost, buck, buck-boost, sepic and cuk [1]. Some of these converters will focus on betterment of voltage gain [2] with a help of currents stored in inductor.…”

In this enormous development of technology, the requirements are new per each day. The needs must be satisfied but fulfilling each requirement will generate new desire or need. The technology is evolving day by day because of this recycling process. The invention of fuel-based vehicles shows some de-merits to evolve and shift over to the electrical vehicles. The proposed paper concentrates its main application to be the electrical vehicles, With an improved form of boost as well as buck converter with high voltage gain and efficiency. This shows close loop operation because of its ability to control a drive or electrical vehicle in the place of load. The bi-directional converter adopts quadratic method in proposed model for highly efficient utilization. This paper focuses on the high efficient utilization of bi-directional converter with quadratic property using proportional integral controller for its switching.

Microgrids based on fuel cells are used to produce energy due to their zero emissions, stand-alone operation, and compact size that facilitates mobility; making research in fuel cell applications essential to support their widespread adoption. This paper proposes two main contributions: the adaptation of a TMDSSOLARUINVKIT microinverter for integration into a microgrid powered by a fuel cell, and the design and implementation of adaptive controllers. The controllers ensure the proper operation of the microgrid and avoid the fuel cell starvation. The microgrid comprises a fuel cell emulator, a TMDSSOLARUINVKIT microinverter, and AC linear and nonlinear loads. The research methodology follows three steps. First, a hardware-in-the-loop approach is proposed to emulate the fuel cell using a real-time target machine and a power interface, utilizing a model derived from the fuel cell manufacturer’s specifications. Then, a detailed model of a flyback converter is obtained to design and implement a control system, consisting of two adaptive controllers, one for regulating the current of the fuel cell and another for controlling the DC-link voltage. The current controller adapts a proportional gain to ensure a desired cut-off frequency and the DC-link voltage controller adapts a proportional and integral gains due changes in the duty cycle, ensuring the proper operation in any operating condition. Finally, the functionality of the microgrid based on a fuel cell is validated through four experiments. The results confirm the effective operation of the controllers ensuring the safe operation of the fuel cell. One experiment is designed to demonstrate the capability of the proposed solution to meet the requirements of rural areas in Colombia.
