Phase-controlled rectification for permanent-magnet downhole alternators

This thesis develops a method of phase-controlled rectification to be used with permanent-magnet downhole alternators. The design faces unique challenges imposed by the downhole environment. The thesis discusses the design, simulation, and construction of the rectifier. A high-side semi-bridge phase-controlled model is proposed. The model is verified in simulation. A prototype rectifier was built and tested using downhole certified components. A controller was designed using the Spectrum Digital TMS320F2812 board. The prototype met all design objectives. The thesis also proposes ways to continue future work.
