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).

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 ...

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 ...

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 ...

ECG interference suppressed using a harmonic generator

Australasian Physics & Engineering Sciences in Medicine, 2009
Non-linear loading of the utilities supply introduced significant electromagnetic field (EMF) interference severe enough to disrupt electrocardiograph (ECG) monitoring and recordings in the new Emergency Department (ED) at the Royal Melbourne Hospital (RMH).

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.

Modeling and harmonic suppression for power distribution systems

IEEE Transactions on Industrial Electronics, 2003
Expansion of voltage distortions along power distribution systems, which is referred to as the harmonic propagation, is pointed out. This is caused by the LC resonances between the distribution line inductances and the power capacitors. This paper presents a modeling and harmonic suppression procedure for power distribution systems.

Differential RF Phase Shifter With Harmonic Suppression

IEEE Transactions on Industrial Electronics, 2014
For the first time, a differential phase shifter with harmonic suppression is proposed. Not only does the proposed structure provide a constant differential phase shift over a wide bandwidth, but it also has good harmonic rejection. Compared to the existing coupled-line phase shifters, the proposed stub-loaded transmission line configurations show good

Single mode ring resonator with harmonic suppression

2014 14th International Symposium on Communications and Information Technologies (ISCIT), 2014
A single-side-access ring resonator for bandpass filter is presented. The characteristics of the resonator were investigated in terms of width and gap of the ring line and coupled-lines on microstrip. It is found that the frequency response and bandwidth of the resonator can be controlled by controlling the width and gap of the ring elements.
