Abstract
A controller of a power converter is described that after switching-on a primary switch of a power converter, detects a voltage that is indicative of a primary current through the primary switch and responsive to determining that the voltage exceeds a direct-current (DC) voltage threshold, switches-off the primary switch. The controller stores a peak value of the voltage while switching-off the primary switch, and responsive to determining that the peak value is higher or lower than a range of target values associated with the peak value of the voltage, the controller adjusts at least one of the DC voltage threshold or the range of target values for a subsequent switching cycle of the primary switch.
