Unified power quality conditioner is one of the advanced forms of power conditioning device, which is a combination of back to back connected series APF and shunt active power filter (SAPF) connected to a common DC link voltage. This topology will facilitates this device to have a reduced dc-link voltage without reducing its compensation capability. This device is mainly used in improving the p...

Abstract A fuzzy-integrated sliding mode-based hybrid controller (FISMHC) attributed to unified power quality conditioner (UPQC) was proposed in this study through implementation with solar integrated fuel cell incorporation of UPQC within sequence designed for active filters series and shunt configurations under shared structure DC-link capacitor deployment. Furthermore, the scheme FISMHC (U-F...

While the unified power quality conditioner based on modular multilevel converter (MMC-UPQC) can be used for recovering of voltage and current in high grids, it is difficult to manage when grid imbalance large. In this paper, a passivity-based control (PBC) combined with sliding mode (SMC) proposed MMC-UPQC improve under unbalance systems. First, according structure MMC-UPQC, equivalent mathema...

The enhancement in electric power quality using a single-stage solar PV integrated Unified Power Quality Conditioner (UPQC) has been discussed this paper. UPQC is the combination of Distributed static compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) having common DC voltage supply link. DSTATCOM compensates for load current associated problems like factor improvement, even odd harmonic...
