  • In this paper, a three phase PWM Watkins-Johnson AC-AC converter for VVCF applications is presented. The PWM Watkins-Johnson AC-AC converter is modelled by using vector DQ transformation whereby the basic DC characteristics equation is analytically obtained. Finally, the PSIM simulation shows the validity of the modelling and analysis.
