2500Hz 16kV High Current Thyristor based Solid State Switch

High-current, high-frequency, high-voltage solid state switches have thus far required a large number of parallel and series connected components, such as MOSFET or IGBT. Such a large number of components increases both the complexity and the cost and failure risks associated with the switch. Applied pulsed power has developed a high current, high frequency, thyristor based switch capable of 5 kA, 2500 Hz operation with 30 kA/mus peak di/dt. Operation of the thyristor based switch to IGBT and MCT based switches at low current, will be compared, and data from the thyristor based switch at high current, shown.
