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

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

Advanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...
