Harmonic resonant filters for power electronics

The European Physical Journal Applied Physics, 2007
The object of this work is to report a passive filter structure dedicated for power applications. The structure is based on a series combination of elementary notch filters resonating at harmonic frequencies of a base frequency (switching frequency of a converter). A calculation of values of the components used for a given performance is presented.

A novel harmonic power filter

PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference, 2003
A novel harmonic power filter system consisting of passive LC filters and voltage source pulsewidth-modulated (PWM) converters is described. This filter system has the merits of both conventional passive LC filters and conventional active power filters. The operating principle and a control scheme for the system are described.

Switching of power harmonic filters

Proceedings of 1994 IEEE Industry Applications Society Annual Meeting, 2002
Power harmonic filters are installed at the AC input terminals of rectifiers, motor drives, UPS, and other nonlinear loads to reduce the distortion of the terminal voltage at the point of connection. The design guide for these filters, such as IEEE Std. 519, assumes a fixed load condition, and does not focus on switching of the filters.

Harmonic filtering in power applications

Conference Record. Industrial and Commercial Power Systems Technical Conference, 2003
One suggested solution to line-current harmonics injected by rectifying power converters is the placement of series-resonant filters across the line supply feeders. For effective filtering, the filter impedance level must be comparable to the source impedance.

Allocation of power harmonic filters using Genetic Algorithm

2012 IEEE 15th International Conference on Harmonics and Quality of Power, 2012
In this paper it is confirmed that the placement of harmonic filters in power systems is not a trivial task. Although it seem obvious the allocation of filters in the buses with the biggest harmonic distortions and/or with the largest harmonic sources, it is going to be proven that these choices are not the best solution regard the network operation ...

Distributed Power Amplifier with electronic harmonic filtering

2009 IEEE Radio Frequency Integrated Circuits Symposium, 2009
Providing all band power amplification and harmonic rejection are objectives with orthogonal implementations. This paper is a review of a new Distributed Power Amplifier (DPA) architecture using programmable frequency dispersion. This frequency domain dispersion is designed to achieve electronic harmonic filtering within the intended frequency band ...

Optimal Design for LC Power Harmonic Filters

International Journal of Power and Energy Systems, 2005
This study describes a novel method for designing LC-type (single-tuned) filters to reduce harmonic distortion. The proposed method minimizes the total cost of the filters, such that the harmonic distortion is within an acceptable range. The filter design problem is formulated as a combinatorial optimization problem with a nondifferentiable objective ...

Compact filtering power divider with harmonic suppression

Journal of Electromagnetic Waves and Applications, 2016
This paper presents a novel power divider with flltering responses. By using quarter- wavelength resonators with a novel feeding structure, both power division and bandpass responses are obtained, and compact size is realized. Discriminating coupling is utilized to suppress the third harmonic to obtain wide stopband. The isolation resistor is connected
