The availability of low-cost high-speed microprocessors has prompted a great interest towards full-digital high performance AC generator sets. This paper deals with the novel application of a multiresonant amplifier instead of a conventional PI regulator in the voltage closed control loop of a diesel-driven generator. An inner current control loop is implemented to provide limitations of the inductor current in case of short circuit and overload. The experimental results show that the proposed converter gives the system superior performance in terms of both output voltage accuracy and stability, in spite of any load variation.
