A decoupled series compensator for voltage regulation and harmonic compensation
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002This paper presents a new power converter topology for the series VAr compensation of AC power systems. The scheme employs a multi-step inverter for compensation at fundamental frequency and a PWM inverter for harmonic compensation. The inverters are decoupled in such a manner that the high-frequency harmonic compensation module uses an inverter of low

Harmonic and interharmonic currents compensation in DC line
2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014In this paper a strategy for the compensation of harmonic currents in DC bus has been proposed. By means of a multilevel converter, low amplitude harmonic currents due to the interaction between primary converters operating in different conditions and connected to the same DC bus, are compensated.

CURRENT HARMONIC COMPENSATION USING PREDICTIVE CONTROLLERS
Journal of Circuits, Systems and Computers, 2004The power quality has become a major concern since late 1980's. There has been increasing interest in studying power quality problems, one of which is the existence of the current/voltage harmonics. In order to eliminate these harmonics, different methods have so far been proposed and developed.

Harmonic Acceleration as a Measure of Vestibular Compensation
Acta Oto-Laryngologica, 1983The results of conventional electronystagmography (ENG) sometimes are confusing. The Hallpike alternate binaural bithermal (ABB) caloric test is helpful diagnostically except for the group of "sick patients that have a normal test". Conventional ENG tests also fall short in the area of objective confirmation of patient progress.

Torque Harmonic Compensation in a Synchronous Reluctance Motor
IEEE Transactions on Energy Conversion, 2006The torque behavior of a synchronous reluctance motor [including the permanent magnet (PM) assisted configuration] is deeply analyzed. An analytical model is developed, showing the dependence of the torque ripple on the rotor geometry. The results of this model allow to individuate the position of the flux--barrier ends so as to minimize the torque ...

A Current Reference Compensation Scheme for Second Harmonic Current Compensator
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020The instantaneous output power of the two-stage single-phase inverter pulsates at twice the output voltage frequency. The second harmonic current compensator (SHCC) can eliminate the influence of the second harmonic current (SHC) in the front-end dc-dc converter and input dc source.

The problem of harmonic compensators location
European Transactions on Electrical Power, 1996AbstractCurrent harmonics can be eliminated in each individual load. Such a compensation generally must be expensive. Harmonics are partly compensated between individual consumers. Therefore, the compensation of group of consumers seems to need lower cost than individual compensation. In the case of group compensation there are two possible approaches.

Modeling, identification, and compensation of friction in harmonic drives
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003Harmonic drives are increasingly used in precision positioning applications such as military radars, wafer handling machines, and satellite cameras. Precision tracking performance of these drives is deteriorated by nonlinear transmission attributes including kinematic error, flexibility, hysteresis and friction.

A Negative Feedback Repetitive Control Scheme for Harmonic Compensation
IEEE Transactions on Industrial Electronics, 2006In this letter, a different feedback structure of the repetitive control that apparently is more appropriate for applications in power electronics is proposed. Moreover, a simple analog-circuit implementation is proposed which is suitable for high-frequency power electronics applications, where digital control is unpractical due to cost and performance
