This paper clarifies the harmonic problems associated with the application of a half-controlled three-phase bridge rectifier, or semiconverter. A comprehensive explanation of the harmonic generation and an analysis of power converter operation with different firing angles is provided. Voltage and current waveforms showing the distortion characteristics of input and output quantities are presented. The performance of a 2nd harmonic filter to reduce even harmonic injection into the system and to improve power factor is evaluated using the Electromagnetic Transient Program (EMTP).<>

The technology to deliver to the market place efficient, low cost, and reliable thyristors with large stand off voltage and large saturation current capability, has led to nonlinear loads that corrupt the commercial 60 Hertz power distribution system. The combined effects of the switching harmonics, the poor power factor of nonlinear loads and the use of capacitors for power factor correction has led to a phenomenon that creates a transmission line resonance that has led to significant destructive failure mechanisms.<>
