Abstract :
A stacked MOSFET switch has been developed and tested. Commercially available MOSFETs (900 V, 8 A) are used to form the stack of 8 in series and 6 in parallel. Each FET is triggered by an optically coupled signal so that all units are controlled simultaneously by a common trigger circuit. Experimental results have shown that such this stacked MOSFET switch is capable of working under the voltage of 5 kV, turning on and off of 75 A in ∼ 30 ns, at the maximum repetition rate of 2 MHz.
