1. A gate driver for driving switches, the gate driver comprising:
a first input for receiving a first signal indicative of a polarity of a voltage;
a second signal indicative of a polarity of a current; and
a plurality of outputs for outputting gate signals for driving the switches,
wherein, in response to a fault condition, the gate driver generates gate signals at the plurality of outputs that depend on the polarity of the voltage received in the first signal and the polarity of the current received in the second signal.
