Effect of Transformer Leakage Inductance on the Three Phase Capacitive Input Rectifier

The characteristics of three phase capacitive input rectifiers which include the effects of transformer leakage inductance have been generated by computer analysis and reduced to a set of design curves. The inclusion of sufficient inductance leads to a three phase commutation mode which in general cannot be accounted ror by a superposition of single phase design curves • The results presented fill a long standing gap in the literature with respect to a practical set of data on the desigo of three phase rectifiers with capacitive input filters.
