Three-Phase, Four-Wire UPQC Topology with Reduced Switching Losses
The paper introduces the modified UPQC topology with reduced switching losses. UPQC is a versatile custom power device which consists of two inverters connected back to back and deals with both load current and supply voltage imperfections. It can simultaneously perform as shunt and series active power filters. The series part of the UPQC acts as Dynamic Voltage Restorer (DVR). It is used to ma...
متن کاملAdaptive Hysteresis Current Control of Shunt Active Filter for Three Phase Four-wire System
In a balanced three phase system, only harmonics of positive sequence(7 th , 13 th ,..etc) and negative sequence (5 th , 11 th ,…etc) are produced. However, the harmonic currents produced by single phase non-linear loads like switch-mode power supplies in computer which are connected between phase to neutral injects third order zero sequence harmonics (3 rd ,9 th ,15 th …etc) (Mehmet et al 2008...
متن کاملA Novel Control Strategy of Three-phase, Four-wire UPQC for Power Quality Improvement
The current paper presents a novel control strategy of a three-phase, four-wire Unified Power Quality (UPQC) to improve power quality. The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor. The realization of shunt APF is carried out using a three-phase, four-leg Voltage Source Inverter (VSI), and the series APF is realized usin...
متن کاملA New Topology of Three-Phase Four-Wire UPQC with a Simplified Control Algorithm
In this paper, a simplified control algorithm based on unit vector template generation (UVTG) is proposed for a stardelta supported three-phase four-wire (3P-4W) unified power quality conditioner (UPQC) topology for the improvement of different power quality problems. Different topologies reported in literature for 3P-4W UPQC use active compensation for the mitigation of source neutral current ...
