IC 1A and IC 1B , which implement an R-S flip-flop, control the potentiometer's wiper direction—up or down. The output of the flip-flop reflects the up/down position of S 1 . The potentiometer's wiper ...

The maximum duty cycle (D MAX) in these applications is limited to 50%. On the other hand, single-switch, resonant-reset forward converters (Fig. 1) are characterized by the absence of a reset ...
