Inductive charging / power

[Russlk]

Well---- I think the circuit must be operating inefficiently. Let me simulate the circuit and get back to you.

 

[Russlk]

The power in the 100 ohm resistor is about 800 mW, so yes use a 1 watt resistor. Also increase the 10K to 1 megohm for better efficiency.

thankyou for your help, i will give those things a try...

cheers

help needed for the primary ckt pls circuit diagram is needed....

What the - ?

Russlk, are you trying to drive the coil through the transistor's base???

 

[jpanhalt]

This thread is almost 5 years old. I doubt Russlk is still trying to solve that problem. But then again, maybe he is persistent.

you can place a traic at primary of transformer and a pic should control this traic trhough opto isolator MOC3021.
pic should control phase angle according to battery condition and current at output.
but i have no code of pic .
thanks
