| Summary: | This thesis presents the design and implementation of a single phase ac adaptor which can be used in a car. A single phase inverter converts a 12 v dc to a 230 v ac voltage with a 50 Hz frequency. The inverter was fabricated and controlled by PIC16F877 microcontroller employing a PWM technique. In this paper UPWM switching technique is first reviewed. Programming was done using Microcode Studio Plus. Subsequently control circuit and power circuit for inverter are discussed. Finally the simulation and experimental results are discussed. The prototype of the inverter was tested with the resistive load and found that total harmonic distortion (THD) is less than 4.6 % voltage. |
