Abstract
Disclosed is a power converter circuit and a method for operating the power converter circuit. The power converter circuit includes at least one converter stage and a control circuit. The at least one converter stage includes an input configured to receive an input power, an output configured to supply an output power, a first electronic switch, and a first inductor coupled to the first electronic switch. The control circuit includes a hysteresis controller configured to drive the first electronic switch based on a current measurement signal representing a current through the inductor, a first threshold signal, and a second threshold signal, and an operating point controller configured to detect an operating point of the converter stage to generate the first threshold signal and the second threshold signal based on the detected operating point.
