Abstract :
The aim of the paper is to present some preliminary ideas in order to overcome the output transformer in series resonant inverters for induction heating applications. By adding a third reactive element to the conventional two element resonant inverter, the output matching transformer can be eliminated, allowing accommodation of the resonant frequency and load with the only drawback being the need for an overdimensioning of the output capacitor bank, and benefiting from inherent short-circuit protection
