25. Gerador de indução associado a inversor PWM operando com frequencia constante
Some alternatives to the three-phase cage-rotor induction machine application in electric power generation were analyzed in this investigation. The proposed generation systems ensure satisfactory energy quality, as they are able to maintainbalanced three-phase voltage, with sinusoidal waveform and constant frequency at 60Hz. These systems are intended to be

26. Contribuição ao projeto, modelagem, simulação e controle de motores de imãs permanentes e comutação eletronica de elevada potencia
The design and construction of permanent magnet converter-fed electronically commutated machines of large power has been the subject of many studies and there are already some of these drives, with power of thousands of HP, in service. This kind of drive involves more phases than usuaUy found in "Brushless DC Drives", and uses different configurations for th
