Abstract
The main objective of the thesis is to design and simulate the main digital control system for push-pull inverter and DC-DC buck-boost converter with high reliability and fast response and minimum cost. The design procedures is starting with design microcontroller based non-inverting buck-boost converter for voltage stabilizing process and voltage source push-pull inverter for inversion process as the following main items:
• ATmega8 microcontroller based non-inverting buck-boost converter system is implemented to produce constant (15 V) output voltage from unregulated input voltage between 8 and 25 V with high reliability using voltage mode control technique.
• ATmega8 microcontroller based 200 W single-phase push-pull inverter is also implemented with single pulse width modulation control technique. The designed system are simulated and experimentally tested on proto-type for controlling the amount of illumination of 100 W filament lamp. The simulation and test results are satisfied for the performance of the design.
