Hi ALL,
This is mohan I have built a induction heater by seeing the circuit in you tube(please see the attachment for the circuit 1),it is working fine but now i need to control the temperature in that core.
I went some of the datasheets in that i found that changing the frequency to the half bridge we can control the temperature in the core so i built the circuit(circuit 2) as attached .
But here when i test the circuit the input current is increasing with decrease in the input voltage(i have used RPS as a input) and bjts are getting heat.
Please check the circuit and suggest me better way to drive the BJT base.
