We present three-dimensional (3D) micro-scale electrical components and systems by means of 3D printing and a liquid-metal-filling technique. The 3D supporting polymer structures with hollow channels and cavities are fabricated from inkjet printing. Liquid metals made of silver particles suspension in this demonstration are then injected into the hollow paths and solidified to form metallic elements...
A new single-stage and boost-voltage grid-connected inverter with low-frequency current ripple (LFCR) reduction was presented in this paper. It can be applied in fuel cell generation system. The signal modulation method was given within a line cycle. In the proposed inverter, an inverter bridge-leg was shared by Boost converter, which decreased the cost and improved the efficiency of the system. The...
The embedded fully self-biased switched-capacitor (FSBSC) with single-inductor high voltage bipolar-output (SIHBO) converter is proposed to achieve the energy and area-efficient driving scheme for the paper-like cholesteric liquid crystal display (Ch-LCD), which becomes the next generation of electronic readers in the consumer markets. As the compact power management module, SIHBO converter can provide...
Nowadays in power system, there are more and more reactive power compensation equipment. As a result, the harmonic from the equipment has become a problem which can not be neglected. The paper examines the harmonic characteristic of TCR, an ordinary kind of reactive power compensation equipment, in theory, then verifieds analysis results and presents the solution to its harmonic problem based on simulation...
