ABSTRACT:
The power supply converts alternating current voltage to a direct current voltage which is in turn converted to a pulse width modulated voltage. A circuit arrangement is provided responsive to the pulse width modulated voltage to produce N output direct current voltages each having a different predetermined value, where N is an integer greater than one. A feedback circuit is provided between the circuit arrangement and the circuit providing the pulse width modulated voltage to provide a substantially constant value for the N output voltages when a varying load is presented to the power supply. A current transformer arrangement is coupled in series in the feedback circuit to provide wide bandwidth and low droop without oscillation for the power supply when the power supply is subjected to a step load (a step from no-load up to full-load).
