摘要

A clocked current supply apparatus for connection to the network with one or several cables has at least one input rectifier, at least one regulator for generating a sequence of current pulses, at least one adapter network for separately transmitting potential and current pulses and a pair of output terminals for each adpter network to which a voltage-controlling element (accumulator, capacitor) is connected. The adapter network (AN) consists of an adapter transformer (TR) and several blocking diodes (DL, DE) that connect the output terminals (KA+, KA-) to the secondary winding system of the adapter transformer (TR). In addition, a regulator that consists of at least one choking coil (L), at least one pair of electronic switches (ES1, ES2) driven by a controller (STG) and one voltage limiter (BGU) is arranged between the rectifier (GR) and the adapter network (AN). The regulator generates a sequence of current pulses from the rectified mains voltage or from a direct voltage preferably connected to the apparatus by switches (SW). The energy of the current pulses flows through the adapter network (AN) to the output.
