Abstract
A new technique for optimizing the power generated by a double output induction generator (DOIG) is established. The proposed control strategy ensures stable operation of the DOIG within a wide speed range without overheating the machine. The proposed scheme employed a controllable rectifier, a DC link, an inverter, and an isolating transformer in the rotor circuit. Variation of firing angles, overlap angle, voltages, and powers with speed are deduced. Experimental results are given. Results showed that twice the rated machine power is generated at S=-1
