Abstract
A switched-mode power conversion circuit can include a switch control circuit including switch control outputs coupleable to switches included in a bridge network, the switches controllably coupling power input nodes to an isolation transformer according to switch states established by the switch control circuit. A current monitoring circuit can be coupled to the isolation transformer, the current monitoring circuit including an output indicative of a current flowing through a winding of the isolation transformer. A sampling circuit can be coupled to the output of the current monitoring circuit to obtain information indicative of a first current peak during a first sampling duration corresponding to a first current polarity established by the bridge network and a second current peak during a second sampling duration corresponding to an opposite second current polarity established by the bridge network.
