Described herein is a method for discharging a DC-link capacitance in an insulated DC-DC converter apparatus comprising a high-voltage side and a low-voltage side, the method comprising the operations of: making, in an initial step, a conversion of the energy from the high-voltage side to a low-voltage side, which comprises modulating the on times of diagonals of switches of a H-bridge for transferring the voltage at the input node onto a reactive circuit; and following upon said initial step, driving main switches and additional switches arranged so as to set selectively in electrical connection the respective first half-winding and second half-winding of a second winding of a transformer with an output node according to a first and another configuration state, in order to carry out a complete discharge of said DC-link capacitance. |
