An Overview on Harmonic Suppression

2018 Chinese Control And Decision Conference (CCDC), 2018
due to the use of a large number of power electronic equipment in the power system and the increase of nonlinear load, harmonic power quality problems become more and more complex. As one of the most important contents in the research of power quality, the harmonic of power system attracts more and more attention.

Rectangular Waveform Generation with Harmonics Suppression

2016 IEEE 25th Asian Test Symposium (ATS), 2016
This paper proposes signal generator (BIST/BOST) algorithms and architectures for mixed-signal IC testing input. They can provide rectangular waveforms approximated to single-tone and/or two-tone signals with harmonics/IMD suppression. Their circuit consists of digital circuit, a 1-bit DA converter with an analog filter.

Miniaturized rat‐race coupler with harmonic suppression

Microwave and Optical Technology Letters, 2014
ABSTRACTThis article presents a miniaturized rat‐race coupler with harmonic suppression. The proposed coupler only takes 15.1% of the area of the corresponding conventional rat‐race coupler. By replacing the traditional transmission line with the proposed stub‐loaded transmission line equivalently, the coupler performances can be retained and size can ...

Comparison of Harmonic Suppression Techniques

2019 12th International Workshop on the Electromagnetic Compatibility of Integrated Circuits (EMC Compo), 2019
To reduce electromagnetic emissions in AM band, harmonic suppression techniques are implemented on the IC level. Literature on harmonic suppression techniques like Digital Harmonic Cancellation and Selective Harmonic Elimination are available in abundance. These techniques are generally employed in low frequency domain (50 Hz line inverters).

Suppression of inverter output harmonic

2010 3rd International Conference on Computer Science and Information Technology, 2010
Using the harmonic characteristics of output voltage of inverter to design an ameliorative filter which can suppress common-mode and differential-mode voltage at the same time. The simulation is done by MATLAB and the results of the simulation show that long cables are allowed to connect inverter and motor for the filter.

The designated harmonic suppression for SPWM

SPIE Proceedings, 2005
SPWM is a critical method used in asynchronous motor-driven area. But harmonic components of inverter output wave impair its application in motor speed control. A new mixed algorithm was proposed for SPWM, which was a designated harmonic suppression technology by way of improved regular sampling in low voltage and low frequency and harmonic ...

Combined Modulation and Harmonic Suppression

2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006
The output of pulse width modulation includes harmonics with invariable frequencies and invariable magnitudes, which are sources of conducted interference and load resonance. Based on the spectrum analysis of switching modulation and sinusoidal pulse width modulation (SPWM), frequency modulation and low frequency amplitude modulation are combined to ...

A ground slot for harmonic suppression

2012 15 International Symposium on Antenna Technology and Applied Electromagnetics, 2012
In ultra low power RF energy harvesting circuits, it is required that incident power is handled efficiently. One such requirement is to avoid re-radiation of higher order harmonics generated in the single or two diode rectenna. In this paper, a ground slot is proposed to eliminate the higher order harmonic resonance, while ensuring a fixed fundamental ...

Cochannel speaker separation by harmonic enhancement and suppression

IEEE Transactions on Speech and Audio Processing, 1997
This paper presents a system for separating the cochannel speech of two talkers. The proposed harmonic enhancement and suppression (HES) system is based on a frame-by-frame speaker separation algorithm that exploits the pitch estimate of the stronger talker derived from the cochannel signal.
