US 6,552,919 B1 · Converter utilizing pulse duration modulation and ripple control

Abstract

A method for use in a power converter which includes: monitoring a magnitude of an input of a power-flow controller; generating a pulse-width modulated signal wherein at least one pulse has width correlated with a difference between a reference and the monitored magnitude; and varying an output power flow of the power-flow controller in response to the pulse-width modulated signal. In another embodiment of the method, the power converter is characterized by a power converter selected from the group including but not limited to a power supply, a power controller, and a power regulator. In one or more various embodiments, related systems include but are not limited to circuitry and/or programming for effecting the foregoing-referenced method embodiments; the circuitry and/or programming can be virtually any combination of hardware, software, and/or firmware configured to effect the foregoing-referenced method embodiments depending upon the design choices of the system designer.
