Functional Description
The input voltage is fed via an input filter to the input
capacitor. This capacitor sources a single-transistor forward
converter. 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. The
control logic senses the main output voltage V
generates, with respect to the maximum admissible output
currents, the control signal for the primary switching

transistor. This signal is fed back via a coupling transformer.
The auxiliary outputs V
auxiliary output's current is sensed and transferred to the
main control circuit using a current transformer. If one of the
outputs is driven into current limit, the other outputs will
reduce their output voltages as well because all output
currents are controlled by the same control circuit.
