Abstract (en)
[origin: WO2007122268A2] An isolated transfer device with a particular topology including a switching step-up voltage circuit on the primary, with a step-up inductance (LB) and an active buffer stage (D<SUB>T</SUB>, M<SUB>T</SUB>, C<SUB>T</SUB>) providing a peak voltage greater than the peak voltage output by the input voltage source (VE) and two pairs of controlled switches controlling application of voltage supplied by the switching step-up voltage circuit to the terminals (E<SUB>p1</SUB>, E<SUB>p2</SUB>) of the primary winding, and a dual alternating rectifier (D<SUB>S1</SUB>, D<SUB>S2</SUB>) with diodes and controlled switches (M<SUB>S1</SUB>,M<SUB>S2</SUB>) on the secondary. On the primary, the voltage at the terminals of the capacitor C<SUB>T</SUB> of the active buffer stage to apply a controlled alternating voltage between the terminals E<SUB>p1</SUB> and E<SUB>p2</SUB> is regulated by controlling the duration during which the controlled switches of the pairs are simultaneously in the closed state. On the secondary, Vs is regulated by controlling the duration during which the secondary switches are simultaneously in the closed state.
