Zvs Induction Heater Circuit Diagram. The zvs driver circuit is a royer type push pull oscillator with a resonated primary that is implemented with fets. This type of oscillator can be used to drive the ferrite core of a flyback transformer to generate high voltage.
It can also drive a high current air core work coil for an induction heater. Let s focus on the zvs circuit. Well this circuit is not the final version i put together.
Just fling the circuit and it goes boaoaoa.
The zvs oscillator is the most complex part of this circuit so i am going to explain how it works. The video below gives a demonstration of this induction heater in action along with another type of instruction on how to build it. When we take a look at the circuit diagram we notice a 2 branched symmetrical structure in the control circuit called royer oscillator which is a circuit that allows self oscillation of an rlc block at its natural resonance frequency. A simple alternative to this may be in the form of bc547 transistors connected instead of the diodes as shown in the following diagarm.
