Single-phase harmonic elimination PWM

Electronics Letters, 2000
A new pulsewidth modulation (PWM) strategy is presented for single-phase inverters which closely approximates in 'real-time' the switching angles of harmonic elimination PWM. The new development is based on the well-known conventional regular-sampled technique and does not require any of the intensive offline computations normally associated with ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Reduction and Elimination of Harmonics using Power Active Harmonic Filter

International Journal of Recent Technology and Engineering, 2019
The Three Phase 4 wire Harmonic Filter is used to mitigate harmonics which is caused by expanding utilization of present day control electronic system and mechanical assembly drives, uninterruptible power supplies, SMPS and so on. These are responsible of producing nonlinear current and accordingly stack in the system with Harmonics. The capacitance of

Runge–Kutta optimization‐based selective harmonic elimination in an H‐bridge multilevel inverter

, 2023
The application of iterative techniques for solving the Selective Harmonic Elimination Pulse Width Modulation (SHE‐PWM) problem, such as the Newton–Raphson (NR) method, can tend to get stuck at local optima in the solution space.

Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon

Advanced Materials, EarlyView.
We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...
