The use of optocouplers for achieving synchronization in thyristor controllers13;

, 1980
The optocouplers replace the synchronization transformers to simplify the synchronizing circuits in AC/DC convertors and in AC power controllers. Simple circuits are described for synchronization of 1-amp;phi; and 3-amp;phi; control circuits. The methods

Damping potential of single-phase bidirectional rectifiers with resistive harmonic behaviour

, 2006
To reduce the voltage distortion in a distribution network, parallel (shunt) harmonic impedances (SHIs) can be strategically positioned in the network. However, to avoid the additional cost of adding SHIs to the distribution network, the SHI function can

Strain‐Adaptive Dielectric Metamaterials via Bioinspired “Ligament‐Bone” Architecture for Ultrahigh‐Energy Capacitive Storage

Advanced Science, EarlyView.
A bioinspired strain‐adaptive ligament‐bone architecture achieves record‐high energy density of 26.1 J cm−3 and 90% efficiency at 600 MV m−1, coupled with a Young's modulus of 2.13 GPa. ABSTRACT Polymer dielectrics for capacitive energy storage face fundamental trade‐offs between breakdown strength, energy density, efficiency, and mechanical robustness.

Analog Weight Update Rule in Ferroelectric Hafnia, Using picoJoule Programming Pulses

Advanced Electronic Materials, EarlyView.
Resistive, ferroelectric synaptic weights based on BEOL‐compatible hafnia/zirconia nanolaminates are fabricated. Lateral downscaling the devices below 10 µm2 enables 20 ns programming with electrical pulses, dissipating ≤ 3 pJ. Experimental results show that final conductance state is set by pulse amplitude, and is largely independent of the initial ...
