Abstract: boost ridley Reference 1, Ray Ridley has presented a simplified, small-signal control-loop model for a boost converter with current-mode control. The following explains how to modify Ridley's model so that it fits a WLED current-regulating boost converter; it also explains how to measure the boost converter's control loop. Figure 1 , , compensating the loop of a WLED currentregulating boost converter is a bit different than compensating the same , small-signal model of a current-regulating boost converter, while Figure 4b shows an even more simplified
