The gate drive device drives a semiconductor device constituting an arm in an electric power conversion device. Before a turn-off start of a drive arm, in a counter arm, a voltage between one main terminal of the semiconductor device and a gate terminal of the semiconductor device is charged to a voltage value that is larger, in a positive direction, than a negative voltage of a negative gate power supply and smaller than a gate threshold voltage of the semiconductor device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gate drive device, gate drive method, power semiconductor module, and electric power conversion device","description":"The invention provides a gate drive device, a gate drive method, a power semiconductor module, and an electric power conversion device capable of reducing a negative gate surge voltage.
