Wireless 12VDC battery charger - supplied by 120VAC, 60HZ

[cck99352]

Developing a design for a wireless battery charger, that can charge 12V batteries from a 120V, 60Hz source.

Want to build in real world, for a child's science fair.

Any suggestions, ideas, or support is appreciated - please help us develop a simulation that can be built in the real world.

Any help is appreciated.

I am able to pay some small amount for expert support - I need help developing these circuits and appreciate any expertise, advise, or support the community can provide.

Please send any inquiries for further discussion to cck99352@hotmail.com so we can discuss this further. The in-progress design is attached to the original post - let us discuss how to progress it and build it in the real world.

Мне понравилась эта идея - заряжающего стола. Можно помощнее сделать и на любой вольтаж

If easier, we can do a typical tablet or cell phone battery, 3.7 to 4.2V?

Can anyone help (here is the in progress circuit).

Please contact me if you have any advice, recommentations, or can help!

-такая схема не пойдёт. Слишком маленький зарядный ток получится. Обратноходовый преобразователь не способен выдать то, что надо. T1- лишний, можно на высоковольтных компонентах собрать устройство. Без снабберов и супрессоров ваша схема будет убийцей ключей и драйверов🤑

Вот получилась такая приблуда, в пол-киловатта мощности.

Для быстроты симуляции источники питания не стал разрисовывать

Hello!

Thank you for advice!

Any recommendations on how to improve? The most important aspect is demonstrating actual wireless power transfer - any support is greatly appreciated.

I am building the circuit you put in your post - thank you!
