Non linear multiplier for switching mode controller

摘要

The use of a nonlinear multiplier in the control loop of DC-DC converters, SMPS (Switching Mode Power Supply) systems and in PFC (Power Factor Correction) systems, and in particular wherein the constant K of the multiplier circuit vary in function of the amplitude of the error signal fed to an input of the multiplier circuit, greatly enhances stability and immunity to noise, especially that coming from the supply rails.
