Abstract
A system comprises an input power stage coupled to a primary side of a transformer, an output power stage coupled to a secondary side of a transformer, a first common node capacitor and a common node resistor connected in series between a midpoint of the secondary side of the transformer and ground and a detector having an input connected to a common node of the first common node capacitor and the common node resistor, and an output connected to a control circuit, wherein the control circuit is configured to dynamically adjust a switching frequency of the system based upon an output of the detector.
