Project - INDUCTION HEATER CIRCUIT

How are these induction heaters work? We will look over the circuit and explain step by step how the oscillating signal is created, how current is induced and how the metal will get hot. Finally we use that schematic and mount a homemade version and see if it works to heat up some metals. So let'... view more
