Abstract
A high speed transfer switch is provided for transferring a multiphase load among a number of multiphase A.C. power sources. If the initially selected source deviates from desired limits, the transfer switch transfers the load to an alternate source on a phase-by-phase basis. Antiparallel-connected SCRs are used to allow the load current in each phase to commutate to zero before the load is transferred to the alternate power source.
