Abstract

The circuit shown in Fig. 1 provides a technique for eliminating nonlinearity of the DC closed loop gain in a forward converter switching voltage regulator. By the addition of a feed-forwerd path using a variable slope ramp pulse-width modulator, the sensing of multiple output switching regulators can be made to have output voltage regulation independent of the input voltage.
