I need a Power amplifier which amplifies a 0-5V Arduino-generated PWM Signal to a 0-12V Signal with 120W, for powering a ZVS induction heater.
Linearity is not important because i can correct the error in software. Maybe it will be useful to convert the pwm signal to a analog signal to amplify it.
I thought about one of these Solutions: Step-up converter or a Class AB Amplifier. I'm not sure what i should do. What would be your solution and why?
