 Power electronic controllers are extensively used in modern equipment. However, they also create problems in system due to harmonics produced by these converters. With the advancement in semiconductor technology, it is possible to use advanced control techniques in power electronic controllers. The objective of the course is to impart knowledge of three-phase converters, power factor improvement techniques used in converters, Harmonic reduction techniques used in inverters, Buck and Boost dc to dc converters, three-phase ac regulator, Cyclo-converters and Multi-level inverters and their applications.

Review of Single-phase converters, three-phase converters, power factor improvement techniques, PWM converter, dc to dc converters, Three-phase ac regulator, Matrix converter, Multi-level Inverters, Current Source Inverters.
