Abstract: This paper presents the theory of a new var regulator used for voltage control of self excited induction generators (SEIG). In this approach the excitation capacitors of each phase are switched individually by IGBTs at the zero crossing of respective capacitor currents, thereby eliminating switching losses and harmonics and reducing component count. Simulation results using Matlab-Simulink are presented and compared with experimentally obtained results. The developed integral control scheme presented here overcomes all the shortcomings of existing control schemes and, in addition to being self-starting is also capable of handling capacitive loads, thus making its application in standby generators acceptable with associated reduction in unit costs.
