THREE PHASE QUASIIRECTANGULAR VSCF INDUCTION GENERATOR SYSTEM

摘要

A plural switch matrix is connected as a direct ac-to-dc converter between an induction generator and an a-c load. The generator provides three- phase output energy which is switched and controlled by the converter, to supply a controlled three-phase quasi-square wave (QSW) voltage to a load. The converter switching provides periodic shorts across the generator terminals, translating some of the mechanical input energy into electrical energy to sustain the generator field. The converter is regulated by gating signals from a combinational logic circuit.
