Design of Push-Pull Converter for High Efficiency Photovoltaic Conversion

This paper design to represents Push-Pull Converter for High Efficiency Photovoltaic Conversion .The energy conversion systems specially dedicated for the conversion of electrical power from solar generators into a grid are evaluate. Lot of systems are basically developed on boosters or inverters counting electronic switches such as MOS or bipolar transistors. The limits of efficiency are speedily reached when high output voltages and high input currents are needed. Behind presentation of some usual classical systems, pointing out their compensation and drawbacks, we propose an original system based on a standard push-pull converter connected through a dynamic modulation control and PID Controller. The main advantage of this combination is the prospect to control the delivered electric power in a wide range between very low to high levels inside the same basic structural design.
