Abstract :
In This Paper, The Variable Input Voltage And Fixed Output Voltage DC To DC Converter For Photovoltaic System (PV System) Is Designed, Simulated And Constructed. There Are Three Main Portions In The Proposed System. They Are Solar Power Sensing System, The Controlling System And DC To DC Converter. In The Solar Power Sensing System, NPN Transistors (2SC 945) Are Used For Voltage Sensor And Logic Converter. In The Controlling System, PIC 16F876A Is Used To Determine The Solar Power Level And Control The DC To DC Converter. It Also Reads The Input And Output Voltage Values Of The DC To DC Converter Using Its Analog To Digital Converter (A/D Converter) And Shows This Value On The Four Seven Segments Light Emitting Diodes (Leds). The Developed Program For PIC 16F876A Is Tested With Proteus Simulation Software. In The DC To DC Converter, TL 494 (Switch mode Pulse Width Modulation Control Circuit) Is Used To Control The Power MOSFET Which Drives The Ferrite Core Transformer (High Frequency Transformer Or Power Transformer).
