Patent ID: RE40907

Claim:
A power supply, comprising: a pair of load terminals; a storage capacitor coupled across said pair of load terminals; first inductance means coupled to said storage capacitor to thereby form a combined circuit; a source of voltage, which voltage includes a direct voltage component and a time-varying voltage component, said source of voltage being coupled to said combined circuit for producing a flow of current therethrough, which flow of current results in division of said direct voltage component and said time-varying voltage component between at least said first inductance means and said storage capacitor, whereby that portion of said time-varying voltage component appearing across said first inductance means tends to cause a time-varying current flow through said first inductance means and said storage capacitor; magnetically coupled inductive means responsive to said time-varying voltage component appearing across said first inductance means, for generating a second time-varying current component in response thereto, which second time-varying current component is similar to said time-varying current flow through said first inductance means; and combining means coupled to said combined circuit and to said magnetically coupled inductive means, for combining said second time-varying current component with at least said time-varying current flow in such a manner as to tend to oppose said time-varying current flow.
