Reduced Sensor-Based Harmonic Resonance Detection and its Compensation in Power Distribution System With SAPF

open access: yesIEEE Access, 2022
Shunt Active Power Filter (SAPF) is widely used for harmonics and reactive power compensation. However, in addition to the harmonics, harmonic resonance also exists in the network, which is prominent in configurations where both SAPF and capacitor bank ...

Harmonic resonant clocking [PDF]

open access: yes2012 IEEE/IFIP 20th International Conference on VLSI and System-on-Chip (VLSI-SoC), 2012
Distributed inductor-capacitor (LC) resonant clocking is a recent, promising technique to reduce the energy consumption in Clock Distribution Networks (CDNs) by recycling the energy on-chip. Even though the majority of power is saved, resonant clocks distribute a sinusoidal clock signal with a 25% slew which increases short-circuit power in the ...
