Abstract

Doubly fed induction generators used in wind energy applications require a source and power converter system to feed variable frequency AC voltage to its rotor. The paper presents a hybrid rotor injection system in which the rotor power can be drawn either from three-phase AC mains or a photo voltaic (PV) panel-battery combination. While drawing power from AC mains, the AC-DC converter used has a soft switching feature and also power factor correction. While drawing power from PV panel and battery, one of the MOSFET switches of the AC-DC converter will be used for boosting the PV panel output. The converter is simulated and the line currents show a low total harmonic distortion (THD). The results obtained on an experimental converter system are also presented.
