Abstract:
An isolated DC/DC converter includes a primary stage, a transformer circuit, a secondary stage, an active clamp, a first current sense node, and a second current sense node. The primary stage includes a primary switching inverter configured to invert the source DC voltage into a high-frequency alternating current (AC) voltage. The transformer circuit adjusts an AC voltage level of the high-frequency AC voltage and outputs an adjusted AC voltage. The secondary stage includes a secondary switching converter to convert the adjusted AC voltage into a secondary voltage, and the active clamp is configured to clamp the secondary voltage to provide an output DC voltage. The first current sense node is included in the primary stage conducts a source current having a first current level, and the second current sense node is included in the secondary stage and conducts a clamp current having a second current level.
