I implemented a parallel LC induction heater using theory. I made a simple square wave Inverter providing a frequency of 20kHz to the tuned LC circuit. The problem I'm facing is that my tank is not drawing any current although the tank is at resonance with the supply. The picture of the output wave across the coil wrt ground is attached. Should I attach a resistance in parallel to the tank? I don't have any resistance in parallel to that. The picture of the circuit is also attached.
@Marla - I have a variable dc power supply with a built-in ammeter and voltmeter. It has a max rating of 30V at 15A. So, that's where I'm measuring the current. The scope is stating the wrong frequency due to switching harmonics (stays constant at 20.2kHz then fluctuates then goes back to 20.2kHz). The switching frequency of Mosfets is 20.2kHz. Component values => L=1.9uH ; C=33uF; fsw=20.2kHz.
