DESIGN and IMPLEMENTATION of a SHUNT ACTIVE POWER FILTER with REDUCED DC LINK VOLTAGE
This paper presents a shunt hybrid active power filter application mainly for current harmonic elimination and fixed reactive power compensation. The proposed system consists of a small rated voltage source active power filter and a series of LC passive filter connected to each phase. Besides, no additional switching filter is required for the current ripples. Effectiveness of the system is con...
متن کاملA Single-Phase Shunt Active Power Filter Based on Cycle Discrete Control for DC Bus Voltage
-A new control method for single-phase shunt active power filter (APF) is proposed. It integrates the DC bus voltage control and active power filter command current generation, according to the periodicity of source current and energy balance concept. The instantaneous harmonic compensation and linear DC bus voltage control are achieved, without complicated and involved control logic, by using ...
متن کاملA DC Voltage Control Strategy for Active Power Filter
Abstract: Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation p...
متن کاملDesign and Control of a Novel hybrid Active Power Filter based on Load Harmonic Currents Separation with the aim of DC-link voltage minimization in voltage source converter
This paper proposes a new hybrid active power filter, including voltage source converter (VSC) based active power filter and Thyristor Controllable LC Passive Filter (TCLC-HAPF) for eliminating harmonic load current components and compensating reactive power. This new structure which is based on the separation of high and low-frequency components of load current idea can reduce the drawbacks of...
متن کاملComparative Analysis between PI and Fuzzy Controllers for Dc Voltage Control of Unbalanced 4 Wire Shunt Active Power Filter
This research proposes a shunt active power filter (SAPF) for harmonics mitigation in order to improve power quality of the electrical network. The reference harmonic current extraction technique used was based on DQ0 power theory under unbalanced non-linear loads conditions for four wire-installed systems. The DC-link voltage plays an important role in SAPF design to guarantee both steady high...
