Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

Advanced Functional Materials, EarlyView.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in

Modeling and digital control of a single-phase quasi-Z-source inverter based on TMS320F28335-DSP

, 2017
Includes bibliographical references.2017 Spring.One important advantage of quasi-Z-source inverter is that it has a quasi-Z-network, which is consisted of inductors and capacitors, between input DC source and H-Bridge inverter.

New modulation scheme for bidirectional quasi z-source modular multilevel converters [PDF]

, 2018
This paper proposes a dedicated modulation scheme for a bidirectional quasi Z-source modular multilevel converter (BqZS-MMC). The operation principle and a suitable PWM method are proposed. The relation between the modulation index and shoot-through duty

Mesoscale Domain Evolution Mechanism during Alternating Current (AC) Poling of Relaxor Ferroelectrics

Advanced Functional Materials, EarlyView.
Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...
