The switch has a gate connected to the gate drive circuit through a gate drive resistor. The gate drive circuit includes a NPN (or NMOS) turn-on transistor and a PNP (or PMOS) turn-off transistor. The gate drive circuit includes a turn-on resistor with a first resistance coupled to the turn-on transistor and a turn-off resistor with a second resistance coupled to the turn-off transistor. The turn-on and turn-off transistors, gate drive resistor, the switching device, but not the turn-on and turn-off resistors are disposed in an integrated circuit to reduce a gate-drive loop inductance. The first and second resistances can be different to adjust the turn-on and turn-off speeds of the switching device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gate drive circuit for power conversion apparatus","description":"An apparatus includes a gate drive circuit and a GaN HEMT switch where the gate drive circuit has a gate drive output to produce a gate drive signal in response to a gate control signal.
