ABSTRACT:
The converter device transforms a changing direct signal generated by a source of direct current, into a signal whose amplitude is substantially greater than that of said changing signal, at least for certain values of this signal. It comprises a first transistor, an inductance with a high overvoltage coefficient wound on a core of ferrite and arranged in the collector circuit of said first transistor, so that one terminal of this inductance is directly connected to the collector of said transistor, a second transistor of which the collector is directly connected to the base of the first transistor, a connecting capacitor between the collector of the first transistor and the base of the second transistor, and a polarizing resistance arranged between the base of the second transistor and one terminal of said source.
