This letter is aimed at designing an electronic load controller (ELC) for a self-excited induction generator (SEIG) on a stand alone application. With constant input power and fixed value of capacitance, the induced voltage varies with the applied load. This letter proposes an ELC scheme whose control strategy is simple and reliable. Antiparallel insulated-gate bipolar transistor (IGBT) switches are used to control the dump load connection and disconnection. The proposed ELC has been tested under several critical situations, providing an excellent voltage and frequency regulation.
