A shutter pulse generator for high speed camera


Abstract:
A shutter pulse generator was designed, which is based on the metal oxide semiconductor field effect transistor (MOSFET). By using the N-channel level shifter for driving switch groups, which consist of Series MOSFETs and controlled by programmable logic device FPGA (field programmable gate array), a high-voltage pulse is achieved with high-speed front edge and back edge, after processing by pulse forming circuit. Experimental results showed that with a load of 1.1 μF the amplitude of pulse is 800 V and the width of pulse is 81 μs, both its front edge and back edge lasted less than 1 μs. The system is anti-jamming and reliable.
