This paper presents a three-phase Active Power Filter (APF) to improve grid power quality. Starting from indirect control strategy which was used only for three legs - three wires it is proposed in this paper to be used a bridge with three legs - four wire. The new control strategy it was named extended indirect control strategy. The extension consists in passing from the control of a three wire active power filter to the control of a four wire active power filter. The proposed active power filter can compensate the current harmonics and correct the power factor. Nloreover, the proposed control strategy allows the line current at the point of common coupling (FCC) to be balanced and sinusoidal even when the load is unbalanced. Consequently the voltage at the PC becomes balance. Simulation results show the validity of the proposed control strategy.

A Selective Harmonic Amplification Method for Reduction of kVA Rating of Current Source Converters in Shunt Active Power Filters Terciyanli, Alper; Ermiş, Muammer; Cadirci, Isik (2011-01-01) This paper describes a new approach to the design of current-source converter (CSC)-based shunt active power filters (APFs) to reduce the converter kilovolt-ampere rating considerably. This design approach is called the selective harmonic amplification method (SHAM), and is based on the amplification of some selected harmonic current components of CSC by the ac-side filter, and the CSC control system specifically designed for this purpose. The proposed SHAM has been implemented on a CSC-based APF for the el...
Highly Integrated 3 V Supply Electronics for Electromagnetic Energy Harvesters With Minimum 0.4 V-peak Input Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2017-07-01) This paper presents a self-powered interface enabling battery-like operation with a regulated 3 V output from ac signals as low as 0.4 V-peak, generated by electromagnetic energy harvesters under low frequency vibrations. As the first stage of the 180 nm standard CMOS circuit, harvested signal is rectified through an ac/dc doubler with active diodes powered internally by a passive ac/dc quadrupler. The voltage is boosted in the second stage through a low voltage charge pump stimulated by an on-chip ring osc...
LCL-Filter Design for Low-Voltage High-Power Grid-Tied Voltage-Source Converter Considering Various Damping Methods Kantar, Emre; Hava, Ahmet Masum (2016-06-30) The limited switching frequency, size and weight concerns, and the stringent limits for the injected grid current harmonics challenge the implementation of LCL grid filters for low-voltage multi-megawatt (multi-MW) renewable energy converters. Traditional design procedures of such filters employed in low power and high switching frequency converters may not hold for a multi-MW filter interfacing a low-voltage converter switching at low frequency to the electric grid. This paper proposes an LCL-filter design...
Investigation on Series Active Filter Compensated High Power Grid-Connected Voltage Source Inverters with LCL Filter Usluer, S. Nadir; Hava, Ahmet Masum (2014-09-18) This paper deals with Series Active Filter (SAF) based damping methods for the LCL filters of three-phase, grid connected, low voltage, high power Voltage Source Inverters (VSIs). The inherent resonance problem of LCL filters is damped via passive or active damping methods. Passive damping methods employing damping resistors create significant power losses reducing the overall system's efficiency for high power inverters. Active damping methods, on the other hand, are not applicable due to inverter's limite...
A Kalman Filter Based Approach for Light Flicker Evaluation of Power Systems Kose, Neslihan; Salor, Ozgul; Leblebicioğlu, Mehmet Kemal (2009-01-01) In this paper, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. In the proposed method, the frequency domain components of the waveform are obtained by Kalman filtering and these compone...
