1. A fault handling apparatus comprising:
a first power converter and a second power converter;
the first and second power converters each including an output terminal and a control terminal, the first and second power converters to regulate voltage or current at their respective output terminals based on a voltage at their respective control terminals, the output terminals coupled to each other, and the control terminals coupled to each other;
wherein the first power converter comprises:
a first detection circuit to detect a fault condition associated with the first power converter, and
a first signaling circuit to generate a first fault signal at the control terminal of the first power converter after the first detection circuit detects the fault condition associated with the first power converter;
wherein the second power converter comprises:
a first fault protection circuit to change an operating mode of the second power converter after the first signaling circuit generates the first fault signal at the control terminal of the first power converter.
