Diffusion radius is an important construction parameter, because it can significantly influence the grouting effectiveness. Theoretical models in predicting diffusion have been practiced, but there are still significant discrepancies between theoretical calculations and realistic results practical construction. One of critical reasons for misprediction time-dependent behavior cement grout, which affected by water-cement ratio (W/C). Therefore, this paper experimentally numerically studies...
This paper proposes a novel non-isolated three-port converter having dual-input and single-output (DISO) for low cost small component counts. A combination of power sources, including fuel cell battery, can be widely used in various applications to achieve high energy density extend battery lifetime. However, its systems complex because two independent converters are required. Therefore, the simple DC/DC is proposed this It have three essential functions: 1) charging discharging operations...
A combination of multiple energy sources, known as a hybrid system (HES), has been considered to increase flight time for unmanned aerial vehicle applications. Two separated or combined converters, which can be defined fully active converter, placed between sources and the load manage flows from sources. This paper proposed novel digital management control strategy mainly comprised mode identification algorithm, realize four crucial functions: 1) regulation output voltage, 2) control, 3)...
This paper discusses an FPGA-based simulation accelerator for power converters, aiming at achieving a time-efficient machine learning (ML)-aided design methodology. The existing methodology converters is mainly based on human experience and decision, which means that the results from different designers differ. In addition, this process can be time-consuming due to necessary human-involved iterations. Recently, ML-aided has shown its promise great candidate shortening circuit while...
This paper proposes an auxiliary circuit with a flexible <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$LC$</tex> resonant tank for high-efficiency totem-pole bridgeless power factor correction (PFC) converter. The proposed enables zero-voltage-switching operation of the totempole PFC To minimize loss circuit, controls slope inductor current by adjusting capacitor voltage level. When main...
This paper proposes a new multi-output structure based on critical conduction mode (CRM) boost power factor correction (PFC) converter. A CRM PFC converter is widely used in small applications. flyback generally employed for auxiliary stages due to simple and low cost. However, there are many lossy components, multiple such as voltage divider, compensator, controller, photocoupler, also required regulate output voltages. It will be more burden the number of voltages increases. Therefore,...
The energy system with a fuel cell (FC) and storage systems (ESS), including batteries supercapacitors, has been considered to extend operation time ensure long life cycles of ESSs in various electric mobility applications, such as unmanned aerial vehicles vehicles. To enable the utilization multiple inputs simple structure, hybrid converter is promising, its management control should be developed cooperatively achieve optimal performance. However, if desired specification or configuration...
