DC-DC converters are the heart of any switched mode power supply (SMPS) system. Rather than using multiple number of DC-DC converters for regulating voltage of each of the outputs in a multi-output SMPS, the reliability and cost-effectiveness can be improved if a single DC-DC converter is used and viable control technique is employed to regulate the voltages effectively. This paper deals with such...
In this paper, a H-bridge VSC (voltage source converter) with a star/hexagon transformer as three phase four-wire DSTATCOM (distribution static compensator) is proposed for power quality improvement in three-phase four-wire distribution systems. The proposed DSTATCOM is employed for the compensation of reactive power for the voltage regulation or power factor correction along with elimination of harmonic...
A new topology of three-phase four-wire DSTATCOM consisting of a H-bridge VSC (voltage source converter) with a star/delta transformer is proposed for power quality improvement in the distribution systems. The proposed DSTATCOM (distribution static compensator) provides the voltage regulation or power factor correction by reactive power compensation along with harmonics elimination, load balancing...
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...
