Wireless Power Transfer Puns

I have been working on a wireless power transmission circuit, but I am facing a lot of difficulties due to the coil. All the circuits available online use center-tapped coils. I do not understand why, and I don't know how are these kinds of coils made. I have tried making ones but they didn't work. Is there a way I can do such a thing without using a center tap? This is an inverter circuit I found online that converts DC to AC.

Does anyone know what exactly would need to be done in order to make wireless power transfer work over long distances or what is the barrier stopping it from doing so? Maybe it's the way electricity flows through the air and/or the fact that it would fry many of the things that get in its way. But perhaps it is just something to do with the machines. I do not know. Is it even physically possible?

I have seen artistic depictions of satellites beaming power down to Earth. So maybe we already have an idea of how it would work.

Hi all,

I was wondering if anybody had some good resources on wireless power delivery in the far field. A naive approach I came up with was using a rectifier circuit after receiving signal via an antenna, although I'm sure that even a complex rectifier circuit breaks down at radio frequency. I'd love to learn more about the topic, so if you have knowledge or experience, please let me know!

Hello,

Have you ever thought about flying cars? Skipping traffic, saving time, and the environment?

I am currently participating in a University of Virginia Darden Executive Education program. In the Design Thinking class, we are developing a response to the design challenge of integrating advanced air mobility vehicles in urban areas and airports by August 2030. Our team is designing a service that allows "pilots" of the Uber-like service to access an electric grid network to charge vehicles while in transit.

We are currently exploring the possibility of using WiGL technology to power autonomous flying cars wirelessly and in-flight.

I am conducting this survey to hear from subject matter experts and automobile engineers on the technical viability and feasibility of a collaboration to integrate flying cars into airports, cities, and communities.

I would really appreciate it if you can respond to the questions in this form with your honest feedback.

In the Qi standard, the operating frequency ranges from 110kHz to 205kHz depending on the system.

In this forum thread, https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/659596/bq51003-power-dissipation-and-heat

it is said that lower operating frequency = higher power and higher operating frequency = lower power, I was wondering why that it.

Thanks for the help!

Hi,

I built a 555 timer on a breadboard as shown in the picture below.

From the right most side, 555 timer (to generate a 270kHz square signal), NMOS (I don't think that I really need it), BJTs (to boost the current of the signal), and Tx inductor coil. Then there is the Rx inductor coil on the left most side along with a schottky diode and a capacitor to convert AC to DC.

However, the power transfer efficiency (PTE) is very low (~3%). The power consumption from the power sources (I use two 9V batteries due to the high current consumption..) is 1.9W, and the power received on the Rx side is 0.058W.

The inductor coils have the same dimensions (26AWG copper wire wrapped in a diameter = 20mm and height = 5mm with a number of turns = 10). I am trying to build a small wireless power transfer system that produces 0.06W power for a medical implementable device.

I know that IWPT (Inductive Wireless Power Transfer) can go up to 40%.

I varied the capacitors for the coils, so it is pretty much at its resonant frequency...

Should I change the design of the coils, or the circuit?

Can anyone with experience help me with this, please?

I am moving into a solid mid game and I need to start thinking about wireless power transfer and how much my power cables can move. I currently have a few advancepower cells. For power cables I am using a combination of cyclic energy cables and enderIO energy conduits.

How does the advance power cells hold up late game, and will the EnderIO cables hold up or is there a better cable I should look at?
