Abstract (en)
[origin: EP0054445A1] 1. Electronic induction heating device comprising an oscillating circuit made up of a capacitor and an inductance coil which performs the function of a primary winding, the secondary winding being constituted by the charge to be heated, this oscillating circuit being connected to the supply circuit via two electronic switches associated with a control circuit, a resistor and a capacitor being mounted in parallel with each of these switches, characterized in that the two electronic switches - for example two thyristors (7) - are associated with a control oscillator (10) which causes them to operate at the resonance frequency of the oscillating circuit (2-3) so as to open and close at the same time, these switches being designed to perform the function of impedances of very high value at the time of opening.
