ABSTRACT- D.C. motors are seldom used in ordinary applications because all electric supply companies furnish alternating current. However, for special applications such as in steel mills, mines and electric trains, it is advantageous to convert low value of DC into high value of DC in order to use D.C. motors controlled by power electronic apparatus. Here the DC motor is controlled power electronic converters through RES system. Although the design of these converters has been presented at the operational level, some fundamental issues such as topologies, analyses, and control have not been thoroughly studied. In this paper, the basic HB TL topology is first presented. This is followed by the derivation of a systematic method of generating TL converter topologies, leading to the derivation of a family of TL converters with improvement and simplification for better functionality and practicality. This paper discusses wide range soft switching solutions to a pulse width

Energy is the convertible currency of technology. Without energy the whole fabric of society as we know it would crumble; the effect of a 24 hour cut in electricity supplies to a city shows how totally dependent we are on that particularly useful form of energy. Computers and lifts cease to function, hospitals sink to a care and maintenance level and the lights go out. As populations grow, many faster than the average 2%, the need for more and more energy is exacerbated. Enhanced lifestyle and energy demand rise together and the wealthy industrialized economies which contain 25% of the world 's population consume 75% of the world 's energy supply [1]. The use of new efficient photovoltaic solar cells (PVSCs) has emerged as an alternative measure of renewable green power, energy conservation and demand-side management [2]. Renewable energy is the only hope and it is the area of latest research which needs a revolution to make an effective solar panel charging system for the regulation of the flow of current to the desired output and saving the battery from receiving extra voltage and increasing the life. 2. Modelling of PV Cell PV generators are neither constant voltage sources nor current sources but can be approximated as current generators with dependant voltage sources [3]. During darkness, the solar cell is not an active device. It produces neither a current nor a voltage. However, if it is connected to an external supply (large

“Energy storage promises to remedy this problem. By generating power when the sun is shining and the wind is blowing, and then storing that power until it is needed, power producers can incorporate increasing amounts of renewable energy resources while overcoming many of their inherent shortcomings.” (Miser, 2015, p.42)

A zero-voltage- and zero-current-switching full-bridge (FB) converter with secondary resonance is another method in this primary side of the converter have FB insulated-gate bipolar transistors, which are driven by phase-shift control and secondary side is composed of a resonant tank and a half-wave rectifier [6]. Without an auxiliary circuit, zero-voltage switching and zero-current switching are achieved in the entire operating range. In this without using additional inductor, the leakage inductance of the transformer is utilized as the resonant inductor. It has many advantages, including high efficiency, minimum and number of devices this topology is attractive for high-voltage
