Abstract :
This paper presents a deadbeat current control strategy for a stand-alone induction generator (IG), working with variable speed and load to regulate both the IG terminal voltage and the dc-bus voltage of the pulse-width modulation (PWM) converter. The deadbeat current controller is a good application for the IG to reduce the total system cost and the required number of sensors. In the proposed system, not a rotary encoder but a new designed phase locked loop (PLL) circuit is used to determine the electric angle. A 2.2 kW laboratory prototype has been built to confirm the feasibility of the proposed method
