Functional Description

generates, with respect to the maximum admissible output

currents, the control signal for the primary switching tran-

sistor.

The input voltage is fed via an input fuse, an input filter, and

an inrush current limiter to the input capacitor. This capaci-

tor sources a single transistor forward converter. Each out-

put is powered by a separate secondary winding of the

main transformer. The resultant voltages are rectified and

their ripples smoothed by a power choke and output filter.

The control logic senses the main output voltage U_o1and

The second output of double output units is controlled by

the main output but has independent current limiting. If the

main output is driven into current limitation, the second out-

put voltage will fall as well and vice versa.
