Abstract
A current-powered converter includes a current source, a switching section connected to the output of the converter, a dispersed inductance being provided between the switching section, and the converter output. A clamping circuit limits the voltage at the input of the switching section. The clamping circuit comprises a capacitor in which energy is stored during at least one phase of the switching cycle of the switching section, and an inductance by means of which the energy stored in said capacitor is returned to the output of the converter.
