GATE DRIVING DEVICE AND POWER CONVERTER
This abstract first appeared for US patent application 20250015706 titled 'GATE DRIVING DEVICE AND POWER CONVERTER
Original Abstract Submitted
a gate driving device comprises: a gate driving unit that outputs power for switching between on and off of a semiconductor switching element; a speed control unit that controls at least one of a turn-on speed and a turn-off speed of the semiconductor switching element; and a speed switching unit that switches at least one of the turn-on speed and the turn-off speed in response to an instruction from the speed control unit. the speed switching unit includes: a plurality of impedance elements (gate resistors, for example); and switches that control power output from the gate driving unit and to pass through corresponding ones of the plurality of impedance elements. the speed control unit controls the switches on the basis of an output current flowing in the semiconductor switching element.
