Functional Description
The input voltage is fed via an input fuse, an input lter, a
rectier and an inrush current limiter to a single transistor
boost converter. This converter provides a sinusoidal input
current (IEC/EN 61000-3-2, class D equipment) and sour-
ces a capacitor with a voltage of 360-370 V DC. This ca-
pacitor sources a single transistor forward converter.
Each output is powered by a separate secondary winding
of the main transformer. The resultant voltages are rectied
and their ripples smoothed by a power choke and an output
lter. The control logic senses the main output voltage
Uo1
and generates, with respect to the maximum admissible
output currents, the control signal for the primary switching
transistor.
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.
