Switching-mode single-phase DC-AC inverters have been widely used in many applications such as AC motor drivers and uninterrupted power supply systems. Among various control techniques, pulse-width-modulation (PWM) is the most effective one generally used to regulate the magnitude as well as frequency of the converter's output voltage. In this thesis, an open-loop asymmetric three-level inverter with a modified PWM approach is proposed. This novel topology with the modified PWM approach has advantages of smaller device voltage, less harmonics and power loss, and more flexible device selection, compared with conventional H-bridge inverter and NPC inverter. Theoretical analysis is completed; digital simulation is conducted to verify the theoretical analysis. Experimental implementation base on DSP is also performed and the results are demonstrated. Moreover, this inverter is applied in a three-arm solar power system. The theoretical analysis and digital simulation for the whole system are also presented.
