Abstract
A gate driver includes: a gate driving circuit configured to generate a gate driving signal for a power device according to a gate control signal; and a driving capacity switch circuit configured to raise the gate driving capacity of the gate driving circuit when a time-variation signal obtained by passing the gate driving signal in the on-transition period of the power device through a high-pass filter becomes lower than a threshold value.
