Self-excited induction generators (SEIGs) are increasingly being used in small-capacity isolated applications for harnessing both conventional and renewable energy resources. These SEIGs suffer from poor voltage regulation even when driven by constant speed prime movers or fixed head hydro turbines. The suitability of these SEIGs to regulate the terminal voltage is a key factor in deciding its use...
A new topology of DSTATCOM (distribution static compensator) consisting of a H-bridge VSC (voltage source converter) and a star/delta transformer is proposed for power quality improvement in a three-phase four-wire distribution system. The star/delta transformer provides isolation to the H- bridge VSC as well as mitigates the zero sequence current in a three-phase four-wire distribution system. The...
This paper addresses several issues concerning the modeling and application of single-phase, single switch, power factor corrected AC-DC high frequency switching converter topologies with transformer isolation. A detailed analysis, simulation and development are presented for forward buck and flyback buck-boost converters with high frequency isolation in discontinuous conduction mode (DCM) operation...
