The IGBT is configured to energize an electric machine. The gate driver is configured to apply an off voltage less than a threshold voltage onto a gate of the IGBT while the IGBT is operating in a saturation mode, and in response to expiration of a delay from a transition from saturation to linear mode, apply a voltage pulse above the off voltage to reduce flyback from the electric machine. The gate driver may be configured to, in response to expiration of a delay from a transition from saturation to linear mode, apply a voltage pulse above the off voltage and below the threshold to reduce flyback from the electric machine."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IGBT gate drive during turnoff to reduce switching loss","description":"A vehicle powertrain includes an IGBT and a gate driver.
