California Energy Commission's (CEC) Public Interest Energy Research (PIER): Reduced Cost Power Electronic Converter for Generator Applications

Principal Investigator: Herbert L. Hess

Duration: 3/15/00 to 9/15/01

An innovative power conversion system to convert energy from a variable-frequency induction machine to a fixed frequency output. A standard CRPWM inverter is simultaneously modulated with two current components. A three-phase balanced variable-frequency current component transfers energy from the generator to the converter. A single phase zero sequence current component at a fixed 60 Hz frequency transfers energy from the converter through a zero sequence filter to load. The system also works in reverse. In this project, simulate the system and build a working prototype in the lab.
