High Voltage Pulse Generator using Semiconductor Devices

Abstract

As a scheme of delivering accumulated energy in short period of time to gain high instant power, pulsed power technology is widely used to generate high power transient electric pulses. In recent years low energy nanosecond range pulse width application has gained a lot of attention. The improvement of solid state switches make it possible to build a full solid state pulse power unit to generate nanosecond pulses. Pulse generators are capable of producing high voltage pulses with fast leading edge rise time. HV pulse generator can be differentiated mainly in two parts where rise and fall time are not critical and in applications where rise time should not exceed 5ns. In the latter application mentioned above would require power semiconductor devices using series/ parallel combinations. The main aim of this project is to design an energizer using flyback topology combined with step up transformer to generate pulse with a rise time of 5ns with peak output voltage of 4 kV at 500 Ω load. The system will be simulated using Psim/Pspice and Gecko Circuits software and when satisfied output will be obtained, the hardware of the same will be implemented.
