Abstract: Flyback inverter is known as a low cost solution for photovoltaic (PV) ac module application. This study presents atwo-switch flyback inverter followed by a low frequency unfolding bridge for fractional horse power water pumping systems. This topology mitigates the problem of high-voltage transients at switch turn off which commonly exists in single switch flybackinverters. Moreover, th...
We have a rough mockup and idea for a machine to saw big rolls of paper and nonwoven. However, we only have experience and a good idea what we want, but no engineering experience / knowledge. We have made a model in Sketchup to get our own idea clear to ourselves, but we need someone to make it into an actual machine design.
We have designed a fan [url removed, login to view],we need our carel controller to be [url removed, login to view] you are interested please contact with me.I will share details.(Electrical Plans,Fans Specs and so on.) P.s We don't have [url removed, login to view] or any related tool for this project.
I am developing smart water bottles, that are two different sizes – 32oz & 128oz. I want them both to have a similar rugged, futuristic design. Both bottles will feature LED lighting, that will notify users of certain things. Both bottles will feature wireless charging, bluetooth, and have sensors that communicate with the dedicated iPhone and android apps. The sensors will monitor, meas...
Rateless space–time block code for mitigating pilot contamination effects in multi-cell massive MIMO system with lossy links
Arduino - ESP8266 aide Bonjour je suis à la recherche de quelqu'un pour mettre en place un ESP8266 avec une sonde de température et un pluviomètre. Les informations devront ensuite être envoyé sur un site internet. Merci de bien vouloir m'indiquer votre coût horaire.
Hello, Freelancers! I need to design simple embedded system that consists of CPU, RAM, and Camera sensor. CPU should be ARM cortex m series. RAM should be over 4GB. Camera should have resolution between 2 and 5 MP. I will discuss in more detail via chat. Please UPLOAD similar circuit design file on google drive and include the link on your proposal so that I can check it first. Best Regards
Please refer to the attached files. I need the following single line built in matlab/simulink. Voltage and Current loops need to be from abc to dq using Park transform, PLL for bus reference, PV arrays require maximum power point curve. The system is in Islanded mode, which means both PV arrays and auxiliary generator (DGs) supply the loads which share the total load demand for achieving a perfect...
