This article presents the implementation of a new voltage controller for a single-phase two-winding self-excited induction generator that is suitable for renewable energy applications, such as bio energy and diesel engine. The proposed voltage controller regulates the terminal voltage within ±5% at varying resistive, inductive, and dynamic loads. The proposed voltage controller uses only one shunt capacitor (Csh) controlled using back-to-back connected thyristors to vary the reactive power for voltage control of the self-excited induction generator. The power loss in this shunt capacitor (Csh) is 2 W for a 5-kW self-excited induction generator, which is much less compared to its counterparts, such as the static compensator. The proposed controller is useful for remote applications for low power generation up to 5 kW. The proposed controller also regulates the system voltage for small variations in the prime mover speed due to its variable input mechanical power as well as during load perturbations.
