US Patent:

6992469, Jan 31, 2006

Filed:

Dec 8, 2004

Appl. No.:

11/008481

Inventors:

Paul Frederic King - Celebration FL, US

Assignee:

Kiawe Forest, LLC - Incline Village NV

International Classification:

G05F 1/46

US Classification:

323283, 323285

Abstract:

A digitally-controlled, DC/DC converter includes at least one switched-mode power stage for the purpose of converting an input voltage (Vin) into an output voltage (Vout); the power stage including at least one controllable switching device, which is turned ON and OFF by a control device with temporal resolution Δt. The converter further includes a duty cycle control mechanism for controlling the duty cycle of the controllable switching device, the duty cycle control mechanism including a mechanism for estimating the output voltage error; a mechanism for estimating the target duty cycle; a duty cycle quantization mechanism for determining, for a target duty cycle estimate, a first set of quantized ON time/OFF time pairs suitable for controlling the switching device; and a selector mechanism for determining the turn ON and turn OFF times of said controllable switching device by choosing, cycle by cycle, an ON time/OFF time pair from a second set of quantized ON time/OFF time pairs, derived from said first set, choosing in such a manner that the amplitude of the output voltage error is continually minimized.

To compensate for the load-dependent effects of parasitics, the second set of quantized ON time/OFF time pairs is adjusted continuously, to insure optimum performance at all load levels.
