Functional Description
The input voltage is fed via an input fuse, an input filter, a
rectifier 3 and an inrush current limiter 4 to the input capaci-
tor. This capacitor sources a single transistor forward con-
verter. Each output 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
an output filter. The control logic senses the main output
voltage
Uo1 and generates, with respect to the maximum
admissible output currents, the control signal for the pri-
mary switching transistor. This signal is fed back via a cou-
pling transformer.
The auxiliary outputs
Uo2 and Uo3 are individually regulated
by means of secondary switching transistors. Each aux-
iliary output's current is sensed using a current transformer.
If one of the outputs is driven into current limit, the other out-
puts will reduce their output voltages as well because all
output currents are controlled by the same main control cir-
cuit.
