摘要：
In this work, the three-phase rectifier with a new connection is presented. The use of the Scott transformer makes a split dc-bus voltage possible and the rectifier operates with unity power factor. Using only two active switches, the rectifier is able to generate symmetrical currents in the line and a balanced split dc-bus output voltage, which is necessary in several applications. Pulse width modulation and instantaneous average current control are used. There are two voltage controls that regulate the output voltage and the split dc-bus voltage. Complete simulation results under closed loop operation are given, as well as results of an experimental setup.
