Switching-mode single-phase DC-AC converters have been widely used in critical applications such as uninterrupted power supply systems and AC motor drivers. Among various control techniques, Pulse Width Modulation (PWM) technique is the most effective one that is commonly used to regulate the magnitude and frequency of the converter's output voltage. With recent revolution in the Digital Signal Processing (DSP) technology, the trend of converter control is moving to DSP based real-time digital control system. Digital control has the advantage of low cost with increased flexibility and accuracy. In this thesis, three open-loop PWM control schemes are evaluated and compared in both time domain and frequency domain. Theoretical analysis and spectrum evaluation have been completed. Digital simulation is conducted for each of the control schemes to verify the theoretical analysis. Experimental implementation based on a TMS320F2812 DSP is presented and finally system experimental results are demonstrated.
A Thesis submitted to the Department of Electrical and Computer Engineering in partial fulfillment of the requirements for the degree of Master of Science.
