Abstract

Improvements in aperiodic generators, of the type intended to be coupled to a load formed by an oscillating circuit whose inductor element may in particular constitute a heating element of an induction heating apparatus, this generator comprising an active oscillation circuit connected between a source of energy and the oscillating circuit of the inductor element, characterized in that the active oscillation circuit comprises a first transformer whose secondary is connected to the oscillating circuit and which comprises several parallel primaries, each primary coupling in series between the source and an active component, and why It also includes a second transformer coupled between the oscillating circuit and the active components to excite the latter.
