Performance and Analysis of a Stand-Alone DC Power Supply Using Self-Excited Induction Generator with Shunt and Series Capacitors and Diode Rectifiers

Abstract

The paper presents the performance of a stand-alone DC Power Supply using a self-excited induction generator. It has been shown that, with a proper selection of shunt and series capacitors, voltage regulation can be improved. The system has been analyzed to find the procedure to estimate the magnitude of series capacitance. Experiments have been conducted to validate the analysis. The system is found to be suitable in applications where the prime mover speed remains more-or-less constant and a restricted load voltage regulation may be acceptable.
