The goal of this thesis was to design, construct, and prove operational a three-phase inverter. This inverter was to incorporate pulse-width modulation control and was to function as a classroom demonstration unit. Before constructing the full three- phase inverter, a single-phase inverter was constructed with four Darlingtons. A pulse-width modulation scheme was developed and applied to the single-phase inverter. Upon slight modification of the control scheme, controllable single-phase inverter operation was demonstrated. With this insight gained, a pulse-width modulation scheme was developed for a three-phase inverter. After adding a third set of Darlingtons to the initial four, the pulse-width modulation scheme was applied and three-phase inverter operation proved successful.
