There is disclosed an alternating current to direct current static converter which includes a three-phase transformer interconnected with two rectifier bridges to produce a twelve-phase connection for direct current output. The twelve-phase connection is provided by coupling input terminals of one of the bridges to corresponding primary input terminals of each of the three phases of the transformer, and coupling input terminals of the other of the bridges to corresponding phase terminals of the secondary of the three-phase transformer. The outputs of the rectifier bridges are then coupled to provide the DC output. The transformer is constructed such that there is a 150 degree phase shift between the primary and secondary voltages of each phase of the three-phase transformer and a 30 degree phase shift between the input voltages to the rectifier bridges. |
