There are many types of power sources that are used for many different applications. In this thesis, a programmable source is designed, built and tested. The programmable source is able to generate three-phase output signals from three different input voltage signals using the ADMC401 DSP board. The programmable source is unique in that it can reproduce any input signal and amplify the input signal. This is done by pulse-width modulation (PWM). The programmable source was designed with gate driver circuits, a motor controller, switches, filters, comparators and other electronic components. Thermal protection and applications for this programmable source are presented in this thesis. Also, test data taken when a squirrel cage induction motor was powered by the programmable source is presented.
