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 کاملPower Quality improvement of a three phase four wire system using UPQC
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract This paper presents two different control strategies applied to Unified Power Quality Conditioner (UPQC) to improve power quality in a three-phase, four-wire distribution system. The two control techniques are Unit Vector Template Generation (UVTG)...
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 ...
متن کاملImproving the performance of UPQC under unbalanced and distortional load conditions: A new control method
This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...
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...
