This "PLECS Model of the Month" video provides an overview of modulating techniques for the Three Phase Three Switch (TPTS) Converter. The model was submitted by Dr. Janamejaya Channegowda, a former PhD Student at Ontario Tech in Canada and currently an Assistant Professor at the Ramaiah Institute of Technology in India.
For more details refer to Dr. Channegowda's paper:
