Abstract
An insulated transfer device with particular topology, comprising on the primary, a switched-mode voltage step-up circuit, with a step-up inductance (L) and an active buffer stage (D, M, C) supplying a peak voltage greater than the peak voltage supplied by the input voltage source (v) and two pairs of controlled switches controlling the application of the voltage supplied by the switched-mode voltage step-up circuit, to the terminals (E, E) of the primary winding and to the secondary, a full-wave rectifier with diodes (D, D) and controlled switches (M, M). On the primary, the voltage at the terminals of the capacitor Cof the active buffer stage used to apply a controlled AC voltage between the terminals Epand Epis regulated by controlling the time for which the controlled switches of the pairs are simultaneously in the closed state. On the secondary, Vis regulated by controlling the time for which the secondary switches are simultaneously in the closed state.
