ABSTRACT:
A power supply or converter has an AC-voltage source to which a number of rectifiers are connected, with at least one of the rectifiers having a switching stage by which, in a feedback mode, energy can be fed back to the AC-voltage source from a DC-voltage terminal and/or from a capacitor of the rectifier. Such an arrangement achieves an energy symmetry among a number of connected users, e.g. back-feeding output stages, with low losses and low cost in terms of circuitry.
