A Research on the DC-Link Current and Capacitance of the Static Excitation Regulator on a 12/3-Phase Dual Stator-Winding Induction Generator

By proper simplifications, the static excitation regulator on the 12/3 phase dual stator winding induction generator is described by the switch-function model. On this basis, the switch-function expression of the DC-link capacitor current is obtained and the physical meanings are discussed, and the detailed exchange procedures between the generator and capacitor are analyzed. Considering the voltage endurance capability of the capacitor and IGBT, and the current endurance capability of the capacitor, the limitation capacitance equation of the DC-link capacitor is proposed.
