Harmonic compensation for three-phase adjustable speed drives using active power line conditioner

2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002
This paper reports the development of an active power line conditioner for high power nonlinear loads such as industrial adjustable speed drives (ASDs). This work is motivated by the fact that the ability of a static power converter to perform effectively as a shunt active filter is limited by the power and the frequency distribution of the harmonics ...

Study on Fuzzy Controller with a Self-adjustable Factor of Active Power Filter

IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006
Active power filter has been proved to be a useful approach to eliminate current harmonics caused by nonlinear loads. This paper proposes a fuzzy controller with self-adjustable factor to control DC-link voltage of active power filter. The distinctive advantage of the fuzzy controller is that its fuzzy control rules can be modified according to the ...

Active Adjustable Coil Receiver for Adaptive Output Power Based on Wireless Power Transfer

International Journal of Circuit Theory and Applications
ABSTRACTThe wireless power transfer (WPT) system operates under variable load conditions. During different stages of charging, the power required by the load varies. Therefore, the WPT needs to adjust the voltage and power in real‐time to meet these differing demands. The power transfer power of WPT can be optimized for variable loads.

A 60 GHz Wideband, Low-Power Active Receiving Antenna With Adjustable Polarization for SNR Improvement

IEEE Transactions on Antennas and Propagation, 2019
In this article, we propose a polarization adjustable active receiving antenna that covers the full 60 GHz ISM band (57–66 GHz) to improve the signal-to-noise ratio (SNR) degenerated by polarization mismatch with the transmitter. The proposed antenna not only controls the receiving angle of linear polarization (LP) but also controls the axial ratio of ...

Active Thermal Control-Based Anticondensation Strategy in Paralleled Wind Power Converters by Adjusting Reactive Circulating Current

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2018
Offshore wind power converters are usually installed in a closed cabinet equipped with water cooling to meet the moisture and salt spray prevention requirements. When the system faces a sudden dip in the wind speed and is subject to a drastic decline in the output power level, the temperatures of the power semiconductors and cooling water drop ...

Performance of automatic gain adjustment in shunt active filters for harmonic damping throughout power distribution systems

2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002
This paper discusses automatic gain adjustment in fully-digital-controlled shunt active filters. This is the first step in cooperative control of the active filters based on voltage detection for harmonic damping throughout power distribution systems.

Asynchronous Motor's Maximum-Efficiency Control Considering Variable Iron Loss Equivalent Resistance by Adjusting the Ratio of Active Power to Reactive Power

2010 International Conference on Electrical and Control Engineering, 2010
A novel asynchronous motor maximum-efficiency control strategy by adjusting the ratio of the motor's active power to its reactive power is investigated. The study shows that once the motor's desired speed is given, the motor will be running at the maximum efficiency by making the ratio of active power to reactive power reasonable, which can be adjusted
