ABSTRACT:
In a complex AC power distribution network (e.g. CATV), a switching mode power supply at a node, automatically operates in a first mode when the input AC power is at a lower potential and operates in a second mode when the input AC power is at a higher potential. A controller switches between modes of operation depending on the input voltage and on the current mode of operation to proved stable switching between modes which in turn provides stable output voltage from the power supply.
