A Composite Selective Harmonic Elimination Model Predictive Control for Seven-Level Hybrid-Clamped Inverters With Optimal Switching Patterns

IEEE transactions on power electronics, 2021
A composite strategy that combines selective harmonic elimination pulsewidth modulation (SHE-PWM) and model predictive control (MPC) for seven-level hybrid-clamped (7L-HC) inverters is presented in this article. By introducing the unified SHE formulation,

Intelligent Transformer Tap Controller for Harmonic Elimination in Hybrid Distribution Network

2021 5th International Conference on Electronics, Communication and Aerospace Technology (ICECA), 2021
Renewables are incessantly increasing in the distribution network to supply the power demand and reduce the dependency on fossil fuel power plants. The power output of renewables depends on weather conditions. Variation in voltage due to changing climate

A 60-Hz Harmonic Eliminator

IEEE Transactions on Biomedical Engineering, 1978
A 60-Hz harmonic eliminator has been designed to remove dc and 60-Hz line frequency and its harmonics. By triggering a 1024-point sliding average on each cycle of the line voltage, the harmonics of 60 Hz and dc are averaged from the input. This average is then substracted from the input to eliminate these components, leaving the rest of the signal ...

Modulation-Based Harmonic Elimination

IEEE Transactions on Power Electronics, 2007
A modulation-based method for generating pulse waveforms with selective harmonic elimination is proposed. Harmonic elimination, traditionally digital, is shown to be achievable by comparison of a sine wave with modified triangle carrier. The method can be used to calculate easily and quickly the desired waveform without solution of coupled ...

Elimination of Supply Harmonics

IEEE Industry Applications Magazine, 1997
The price of the extensive use of power electronic devices is becoming clear: increasing harmonic "pollution." The greater amount of harmonics being introduced into power distribution systems is of concern to both power consumers and power companies. First, a brief look is taken at background information which describes harmonic sources, effects, and ...

Optimal harmonic elimination control

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
Harmonic elimination and control has been a widely researched alternative to traditional PWM techniques. The equations that govern harmonic elimination have multiple solutions based on different switching angles. Each solution will result in the uncontrolled harmonic content having a unique distribution of energy. To determine which solution is optimal,

Extension of real time harmonic elimination theory to the traditional selective harmonic elimination

2016 8th International Conference on Modelling, Identification and Control (ICMIC), 2016
Generally speaking, almost the existing method used to implement the selective harmonic elimination in real time based on look-up table, which will consume lots of memories of the embedded processor. This paper propose a method that extends the real time harmonic elimination strategy based in modified carrier signal theory to the results obtained by ...

Harmonic elimination for PWM inverter

2017 International Conference on Consumer Electronics and Devices (ICCED), 2017
For a PWM inverter system, the output ac current is expected to be a sinusoidal waveform after filtering; however, PWM inverters have two drawbacks causing distortion of output waveform. One is the presence of harmonics, and the other is the variations of the system parameters.
