摘要： Single phase to three phase dynamoelectric converter for generating three-phase current from a single-phase input comprising a three-phase electric motor generator having first, second and third Y-wound stator windings, a bank of run capacitors connected between the first powered stator winding and the third unpowered stator winding, a normally closed potential-type relay with its winding connected between the second and third stator windings, a normally open slave relay with its winding connected between the first stator winding and the potential relay winding through the set of normally closed potential relay contacts, and a bank of starter capacitors connected between the third stator winding and one of the slave relay open contacts adapted to provide phase shifted starting power to the third stator winding when the single phase energy is applied and disconnect from the third stator winding to allow the converter to run and produce balanced three-phase power that can be drawn from all three stator windings for use to start and drive externally located three-phase motors.
