Abstract:
A system may include a switch, a gate driver, and a signal conditioner. The switch may couple to a load. The gate driver may generate one or more gating signals to control one or more operations of the switch. The signal conditioner may receive an input signal associated with the switch and generate a modification signal that may modify the one or more gating signals based on the input signal. The modified gating signal may be used to reduce an amplitude of a voltage transient received by the switch to below a voltage threshold.
