Abstract
A supply generator for an oscillating circuit, includes an inductance (L) and a resonant capacitor (C, C), for operation at a fixed frequency and also includes at least one pair of transistors (I, I), operated on a variable cyclic regime for modifying the power. The generator includes a first diode (D) between a first transistor (I) and the supply for the generator and a second diode (D) between the junction point of the inductance (L) and the resonant capacitor (C, C) and the junction point of the first transistor (I) and the first diode (D). The invention is of particular use for supply of the cooking rings on an induction cooking hob.
