This senior project report describes the process of designing a unipolar inverter. This high low, unipolar inverter utilizes switches in which a pair operates in high frequency while a second pair operates in low frequency. The purpose of this project is to convert a range of high DC voltage and convert it to an AC output voltage of 120 Vrms with a power rating of 100 W. Nonetheless, this particular unipolar method of implementing pulse width modulation results in harmonics at multiples of the fundamental frequency leading to easier filtering. However, the switching loss increases because of the complex switching circuitry. Overall, this report focuses on the design, construction, and testing aspect of the inverter project.
