Abstract
A circuit for use in an LLC converter to control diode conduction time includes a secondary side controller, the secondary side controller configured to monitor voltage, measure a diode conduction time for the LLC converter, in response to determining that the diode conduction time is greater that a target time, increase the on-time for the first switch, and in response to determining that the diode conduction time is less than a target time, decrease the on-time for the first switch.
