Abstract
This invention generally relates to saturation detection circuits, in embodiments for substantially lossless detection of saturation of power switches in power integrated circuits. We describe a saturation detection circuit for detecting saturation of a power semiconductor device, the circuit including a said power semiconductor device having an input terminal and an output terminal, a second semiconductor device connected across said input and output terminals of the power semiconductor device, and a circuit responsive to a current flowing through the second semiconductor device to detect the saturation of the power semiconductor device.
