Pulsed MOSFET based linear transformer driver
… power applications. This thesis focuses on the design of a MOSFET based pulsed power system capable of generating 2.2kV, 200A pulses with turn on and turn off times of less than 10ns and 20ns respectively. In order to achieve the target specification, a high speed current source MOSFET gate …

A Wide Bandgap Silicon Carbide (SiC) Gate Driver for High Temperature, High Voltage, and High Frequency Applications
… and switching speed. Integration of gate driver circuitry on the same chip, or in the same package, as the power device would significantly reduce the parasitic inductance, require far less thermal management paraphernalia, reduce cost and size of the system, and result in more …

Gate Driver for Phase Leg of Parallel Enhancement-Mode Gallium-Nitride (GaN) Transistors
… are higher. The worst-case performance of this design is limited by both the gate driver and the device shortcircuit robustness. Due to the fast switching speed of the GaN HEMT, the false turn-on phenomenon caused by the Miller effect can be a problem. A shoot through may occur with one switch …

Investigation of Power Semiconductor Devices for High Frequency High Density Power Converters
… power converter applications have been investigated. Firstly, the methodology is developed to evaluate the power semiconductor devices for high power density applications. The power density figure of merit (PDFOM) for power MOSFET and IGBT are derived from the junction temperature rise, power …

Series-Connection of Silicon Carbide MOSFET Modules using Active Gate-Drivers with dv/dt Control
This work investigates the voltage scaling feasibility of several low voltage SiC MOSFET modules operated as a single series-connected switch using active gate control. Both multilevel and two-level topologies are capable of achieving higher blocking voltages in high-power converter applications. …
