PCT No. PCT/FR96/01330 Sec. 371 Date May 7, 1998 Sec. 102(e) Date May 7, 1998 PCT Filed Aug. 29, 1996 PCT Pub. No. WO97/08812 PCT Pub. Date Mar. 6, 1997The invention relates to a continuous voltage converter with soft switching, comprising a transformer (Np, Ns) whose primary is particularly of the type with a half-bridge mounting and is adapted to be connected to a source of input voltage (Ve) by means of two electronic switches (INT1, INT2) and whose secondary, of the mono-alternating type, is adapted to be connected to a load by means of an inductance in series (L2) and means (1 to 3, G1, G2) to control alternatingly the two switches, at fixed frequency, according to a regulation by modification of the pulse width as a function of the output voltage (Vo), so as to provide to said primary a switching at zero voltage, said converter being characterized in that said secondary comprises moreover a resonant circuit (L1, C1) so as to provide for said secondary a quasi-resonant switching at zero current.
