Abstract

Continuous-alternating static converter device, especially for the supply of a fluorescent tube, of the type comprising two transistors with the emitter to ground, whose collectors are coupled to each other by capacitance, and are connected by windings at a mid point, taken to the supply dc voltage, and whose bases are joined to each other by an inductance coupled to the collector windings, constituting a base voltage generator, characterized in that an auxiliary supply is provided to supply the bases of the two transistors with current, supplying this power supply the necessary current for the correct saturation of the aforementioned transistors, by means of two resistors of appropriate value.
