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 in-
put current (IEC/EN 61000-3-2, class D equipment) and
sources a capacitor with a voltage of 360-370 VDC. This
capacitor sources a single transistor forward converter.
Each output is powered by a separate secondary winding
on the main transformer. The resultant voltages are recti-
ed and their ripples smoothed by a power choke and an
output lter. The control logic senses the main output volt-
age
Uo1 and generates, with respect to the maximum ad-
missible 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.
