Development of a Universal Controller for Converter Based Switched Reluctance Motors

This dissertation covers the design procedure of a 8/6 switched reluctance motor from the first principles. The methodical approach to designing the machine is one of the major objectives of this paper. The calculation of the unaligned inductance follows the basic principles of electromagnetic. The procedure for calculating voltage, current, speed and losses for various rotor positions has been developed. A detailed procedure to calculate the eddy-current losses was described. The process of finding the hysteresis losses does not rely on approximate flux profiles. Instead accurate flux plots are used to find the hysteresis losses. The calculation and documentation of the iron loss is one of the significant objective of this paper. The dissertation describes the design procedure for a SRM drive using the new voltage source inverter configuration. The design procedure was verified with computer simulations and experimental verifications of the drive have been done. A SRM drive to PID control has been developed. The dissertation shows the implementation of SRM drives using a DSP based controller and a single converter configuration.
