Symmetrical Components Definition and Analyze for Power Electronic Converters in Non-Sinusoidal Conditions
Authors: ,
Abstract: As symmetrical components are very useful tools for power system analyzing in unbalance condition and defining phasor is hard for power electronics because of their switching behaviors, Time variable phasor is defined for power electronic wave forms at the first. Then some methods are proposed and evaluated for defining symmetrical components for power electronic converters. These methods are developed for zero, positive and negative circuits of a three phase half wave rectifier. The final proposed method satisfies ABC to ZPN transform and vice versa and is tested with harmonics in voltage source. This study is started and has many steps to complete in future.
