Abstract
The invention relates to an isolated resonant primary side switched converter (), comprising a galvanic isolation stage (), an auxiliary winding (L-) on the primary side () of the isolation stage () which is magnetically coupled to at least one secondary side winding (L-, L-) of the isolation stage (), wherein the auxiliary winding (L-) is configured to detect a feedback signal as to a secondary side voltage, and a control unit () configured to sample the feedback signal, in each or every nswitching cycle, during a sampling period in which a current is flowing on the secondary side () of the isolation stage (), and to process the sampled signal for a feedback control of the secondary side voltage by controlling the switching operation of a primary side switch (M, M).
