Abstract
An active clamp circuit for a power converter having a transformer includes a switch having a drain node, a gate node, and a source node, the drain node configured to be connected to a first terminal of a primary winding of the transformer, a capacitor having a first terminal connected to the source node, and a second terminal to be connected to a second terminal of the primary winding, a gate driver coupled to the gate node to control the switch and having a high-side input node and a low-side input node, the low-side input node being coupled to the first terminal of the capacitor, and a voltage regulator to: i) receive an input voltage from the second terminal of the capacitor, and ii) provide a regulated voltage to the high-side input node using the input voltage and being of a sufficient voltage level to control the switch.
