Application of a Stabilizing Method Using Periodic Threshold to Current-Controlled DC/DC Converters

We consider current-controlled DC/DC converters. The controller is composed of comparator and RS-type flip-flop. Previously, we showed that periodic threshold, which is applied into the comparator, has stabilizing effect for circuit behavior. However, the demonstration of the application of the stabilizing method is not reported at all. In this report, we show an example of the application for current-controlled DC/DC converters. First, we show output characteristic of photovoltaic module. Next, we explain circuit dynamics of DC/DC boost convener fed with photovoltaic module. Finally, we discuss stabilizing effect of periodic threshold.
