Abstract

In modern contest the world is moving from conventional energy sources to the renewable one. It is due to its greater abundance and environment friendly characteristics. Solar energy is one of the most reliable and never ending renewable energy sources. This paper presents a method to transfer the peak power of solar photovoltaic module to grid. A unique relationship between open circuit voltage and voltage corresponding to maximum power for the solar module ELDORA40 is developed by simulation in Matlab/simulink. Single Phase Fully Controlled Converter with RLE load is used in inversion mode to convert the solar dc into ac power. Inverter thyristers are triggered by pulse generated by microcontroller. Microcontroller programmed to generate pulse such that peak power of solar module is transferred to grid. Result obtained by experimental setup is satisfactory. The use of microcontroller based control circuit provides us large number of advantages. It reduces size and cost of controller significantly. The efficient control of delay angle is the main advantage. Besides this it provide more versality and greater scope for further improvement just by changing the program but not hardware configuration. The performance of controller is found satisfactory. In general switching control mode as well as specific application mode for solar photovoltaic grid interactive inverter.
