Many applications exist requiring high voltage switching in the tens of kilohertz rates with peak currents at the thousands of amps and blocking voltage at the thousands of volts. High-voltage, high-current thyristors provide low forward voltage and high peak current rating versus active area but suffer from long recovery times. To achieve high frequency operation would have required the use...

Poster Presentation
In many accelerator applications requiring a fast-kicker magnet, radiation generated by particle beams can limit the physical proximity of the modulator to the magnet. It is typical that the modulator be located hundreds of feet away from the radiation environment, increasing the complexity and cost of the modulator and cabling.
The main susceptibility of the modulator to radiation-induced...

A 6kV inductive voltage adder has been designed to drive 50 ohm stripline kicker magnets for an upgrade to the Advanced Light Source at Lawrence Berkeley National Laboratory to a diffraction limited light source. Several features were included in the design to allow damping of potential oscillations and optimizing the rise and fall times. A prototype of this inductive voltage adder has been...

A challenge in fast switching of voltage-controlled power semiconductor devices such as MOSFETs and IGBTs is fast charging of the gate capacitance. As gate drive circuit and device leads both involve stray inductance, the rise rate of the gate current is limited. To achieve higher current rise rates, an overvoltage might be applied to the gate leads (so called gate-boosting) [1]. In this work,...
