ABSTRACT:
A circuit for converting a three-phase alternating voltage to a rectified unidirectional output voltage including a three-phase full-wave bridge rectifier rectifying the three-phase voltage and supplying a first unidirectional voltage and a line selector providing a second unidirectional voltage representing the summation of selected segments of the three-phase voltage. The first and second unidirectional voltages are summed via respective choppers, transformers and a rectifier to provide a unidirectional output voltage.
