Application and Analysis of Transmission Line Load in High-Voltage Fast Pulse Circuit

A new method of transmission line load, which can improve performance of high-voltage ultra-fast pulse generator circuit, is proposed. Substantially, transmission line load is introduced based on conventional circuit. Theories of impedance matching and transmission line signal reflection are combined, and performance of trailing-edge is improved greatly. It is proved by theory analysis, simulation and experiment, compared with conventional capacitance load, not only sharp front-edge is kept, but also performance of trailing-edge is improved greatly, insufficiency of capacitance load is fetched up, and pulse width can be stepping controlled. It is important to research on laser pulse and synchronous sensor in high speed rotating-mirror streak camera and so on.
