Abstract:
An energy converter for supplying electric energy from an energy source to a load, the energy converter comprisinga transformer having a primary side and a secondary side, the secondary side being adapted to be connected, in operation, to the load, at least a first and a second series-arranged, controllable switch to be connected, in operation, to the energy source for generating an alternating current in the primary side of the transformer, diodes arranged anti-parallel to the first and the second switch, and a control device for generating control signals with which the first and the second switch are opened and closed, the control device comprising detection means for generating a detection signal when the energy converter is operative in a capacitive or near-capacitive mode, wherein, for the purpose of generating the detection signal, the detection means are adapted to detect a voltage jump which occurs at a node between the first and the second switch when the first or the second switch is closed.
