Wireless current limited driver...

[Hiemal]

Hey all, so... I had this wireless power thing sitting around in a box under my bed for a bit, and decided to attempt something with it;

A ZVS wireless power transmitter, current limited!

A ZVS driver is a current fed oscillator; meaning that it acts very similar to how laser diodes act. It'll take as much current as it can from a source.

Thinking this through, I decided to use one of my own proprietary driver designs. A buck boost laser diode driver, capable of accepting either one OR two li-ion cells.

Pics!

You can see the driver board on there :3

LED light!

The driver is set to 430 mA. It's boosting to 5 volts, from a single li-ion cell. It draws about 730 mA total from the cell.

In total the driver is drawing about 2.15 watts total from the battery.

Pretty neat huh!?

Very cool.

What you seem to have there is an Air Core transformer...:yh:

That's going to need a big host :thinking:

Onono, the entire thing isn't the driver silly!

The driver itself measures about 12.7 mm by 9.7 mm.

The rest of the bulk in the pictures is the ZVS itself. ;P
