This thesis involves the construction and testing of a Slip Energy Recovery System (SERS). The principle component of the SERS is a wound rotor induction machine which allows for extraction of slip power from the rotor which in turn provides a means of speed control. Induction machines normally operate at a constant speed, but SERS offers a method of speed control which increases efficiency by returning the slip power back to the system. In this research effort, various tests required to analyze speed range, signal waveforms and power flow were conducted. Additionally, an analog and a microprocessor based control scheme were implemented for speed control. A number of studies are presented to validate and contrast the proposed circuits. The system data collected during validation studies are compared against the theoretical Operation of the SERS. After construction, alternative topologies are investigated in order to assess the configuration that provides an optimal speed range. A baseline was established and it is shown that the location of the transformer in the SERS has a significant influence on the speed range. Results from further testing of the baseline configuration revealed that in regards to waveforms and power flow, the system responded as expected.
