ABSTRACT:
A converter circuit for an inductive load, such as the phase windings of a switched reluctance motor, uses only n-switches for n-phases. In a four phase machine, each of three of the phases is serially connected with a switch across one voltage source. The remaining phase is serially connected with a switch across another voltage source which receives the inductive energy returned by the other three phases. This returned energy is used to energize the fourth phase. A generator converter is also disclosed in which the energy in the fourth phase is used to provide the excitation for the other three phases.
