Abstract :
A PWM voltage-source inverter is used in order to improve the electrical characteristics of an isolated induction generator. The electronic converter allows achievement of a better system behavior in many aspects: voltage regulation, frequeney stabilization and reactive power compensation. The PWM inverter DC voltage is the control variable of the generator speed governor, therefore the system power balance and the generator voltage regulation is accomplished by the DC voltage control, which is exerted by the speed governor. Both simulation and experimental results demonstrated that the system is stable, robust and an effective source of regulated three-phase voltages
