Claim 17:
18. A gate driving method for driving a gate of a switching device, comprising:
switching a slope of a gate current of the switching device, within a turn-on period of the switching device, from a first constant slope during at least a first part of the turn-on period to a second constant slope more negative than the first constant slope during at least a second part of the turn-on period after the first part of the turn-on period; and
an input to the switching unit, the input having two levels in operation: an ON level and an OFF level, wherein
the first part of the turn-on period is after a device current starts to flow in the switching device, and
a turn-on signal is continuously input to the switching device during the turn-on period, the turn-on period being a single cycle of the input to the switching unit at an ON level.
