DC VOLTAGE CONVERTER WITH SEVERAL ISOLATED REGULATED OUTPUTS

摘要

The converter has a resonant circuit for producing a mono-alternation resonant current in a secondary winding (Ls) and charging a capacitor (Cs1) so as to produce a main regulated voltage (Vs1). An inductive circuit is connected between the winding and a charge capacitor (Cs2). The inductive circuit generates a current for charging the capacitor (Cs2) when a part of the alternation of the resonant current circulates in the winding and produces a post-regulated voltage (Vs2). The capacitor (Cs2) has an end connected to an inductance (Lr) through a switch (T3).
