“…Currently, most DC-DC converter such as the buck-boost converter, CUK converter, Single-Ended Primary Inductor Converter (SEPIC) and the fly back converter are designed to perform the requirement of specific applications [5]. These converters are built with only an active switch which is commonly MOSFET, a diode and an inductor [6] Single-Ended Primary Inductor Convertor (SEPIC) was chosen as this converter takes in a range of input DC voltage and increases or decreases the output voltage. This can be done by controlling the duty cycle of a pulse to the MOSFET.…”

The invention of electricity has become an essential part of every aspect of the society globally. With the increasing demand for the electrical appliance and electronic gadgets, this has also increased the consumption of energy significantly. As a result, we experience power outage which causes huge losses to industries. Hence, this research address if it is sustainable to use alternative energy in the form of bicycle power to charge a mobile phone. Bicycle power is a form of renewable energy that does not require the burning of fossil fuel to generate energy. The objective of this study is to design a mobile phone charger electrical circuit which consist of the integration of electrical components. Subsequently, the energy and power consumption between the conventional charging method and pedal powered charger can be assessed. This analysis is done to determine if pedal power is an economically sustainable solution to generate electricity. In this analysis, three selected dynamos hubs were assessed based on the performance data during low, medium, and high speed. The relationship between voltage, power speed, and time were obtained from the performance data and calculations. The chosen dynamo hub was the mid-range model, Shimano DH-3D72 which produces sufficient power at low and high speed to charge the mobile phone. The next analysis was the DC-DC converter topology which was essential to ensure that the output voltage was capped at 5V. The results have shown that a SEPIC converter was chosen based on the designed electrical circuit and application used. The third analysis was the selection of ultracapacitor which was needed to store energy during high speed and discharge energy during low speed. The selected ultracapacitor was justified with relevant calculations and further simulated in an analog circuit software, LTSpice XVII. All the selected electrical components were integrated to form a complete electrical circuit and were simulated under various inputs condition. The outcome of the results shown that the efficiency of the charging system was improved by 30%. The payback period for this system would require only 406 days which is equivalent to 1.1 years.

The aim of this paper is to analyse the performances of the fuel cell directly connected to a variable load. The hydrogen represents one of the main green energy of the future. The fuel cell is the engine responsible of converting hydrogen into electrical energy. Thanks to its higher efficiency, low operating temperature and its easy maintenance, the Proton Exchange Membrane Fuel Cell is used in transportation such as hybrid vehicles and Fuel Cell Electric Vehicles. Power converters are used in fuel cell systems to control the flow of the power and regulate the load voltage. In addition, power converters are designed to reduce the voltage and current ripple of the fuel cell. In aim to investigate the fuel cell performances in case of converter fault and direct connection to the load, this work is conducted. Experimental tests were performed using the Fuel Cell Nexa 1.26 kW system. The experiments are performed under diverse operating situations representing the load current profile of the New European Driving Cycle of the electrical vehicle whether static and dynamic ones. The experimental results show good performances of the fuel cell connected directly to the load to provide the required load current. However, the same results prove the need to the power converter to reduce the current ripples.

The proton exchange membrane fuel cell (PEMFC), one of the many fuel cell varieties on the market, is distinguished by its low temperatures of operation, high reliability, and extended lifespan. The fuel cell system's maximum output can only be achieved at one specific operating point under varying operating circumstances. Hence, it is essential to get the most power possible from the PEMFC for improved functioning and optimal exploitation of grid systems. Thus, the design of a maximum power point tracking (MPPT) controller for a PEMFC power system using an amplified salp swarm optimization (AS2O) algorithm is focused on. Here, an interleaved Luo converter is also used to produce a regulated output voltage with less switching stress and frequency. Moreover, the proposed work intends to effectively satisfy the energy demand of grid systems by obtaining the maximum electrical energy from the PEMFCs with less harmonics and low system complexity. The simulation and performance results of the proposed AS2O‐MPPT controlling model are validated and compared using several parameters using MATLAB/Simulink tool. Using the proposed controlling technique, the total harmonics distortion is reduced up to 1.16%, with the settling time of 0.0062 s, rise time of 0.0010 s, and peak overshoot of 0.255 W.
