Upper and lower gate drive circuits supply gate drive signals to the upper and lower transistors. Each gate drive circuit includes an active clamp for deactivating the upper and lower transistors. The transistors are comprised of semiconductor devices, each having respective gate, collector, and emitter terminals. Each pair of gate and emitter terminals is adapted to provide an enhanced common source inductance therebetween. Each gate terminal is adapted to be tied to a ground voltage of the drive circuits. Each respective active clamp is comprised of a p-channel MOSFET having a source terminal connected to the gate terminal of a respective transistor and having a drain terminal connected to the emitter terminal of the respective transistor bypassing the respective enhanced common source inductance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active gate clamping for inverter switching devices using grounded gate terminals","description":"An inverter for an electric vehicle comprises a phase leg having series-connected upper and lower transistors between a positive bus and a ground bus.
