Abstract

An ac-dc converter circuit has input terminals designed for a balanced polyphase supply. The output a.c. voltage is obtained directly without the use of an intermediate d.c. stage. The output differs from the input in at least one property, such as frequency, amplitude, phase angle or phase shift. There is a number of two-way switches which couple the input to the output independently. The control system has attenuators which generate a series of modulatd pulses. The number of pulses is each train is equal to the number of phases of the input system. Each phase is in turn, connected to each phase of the output system by regulating the switching sequence.
