Abstract:An all solid-state multi-turn linear transformer driver is designed for the application of pulse power techniques with high-voltage, large-current and wide pulse width in pulsed electromagnetic biomedical applications. The magnetic core of the linear transformer driver (LTD) pulse generator adopts the method of multi-turn winding, which can output pulse of wide pulse width. The isolation of drive power supply and energy charging with co-direction winding of LTD modules is designed, and the isolation voltage of magnetic cores is the working voltage of LTD modules. The multi-turn LTD pulse generator is composed of 10 LTD modules. Each module is connected in parallel by 18 energy storage capacitors and MOSFETs discharge switches, and its synchronous drive circuit is designed. Through the analysis and selection of the components model and circuit, a modular all-solid-state pulse generator based on multi-turn LTD is development, which can output pulse parameters for the voltage amplitude 0~5kV, the output pulse current up to 500A, pulse width 200ns-5μs, pulse rise time 30ns, falling time 16ns, and its parameters can adjusted flexibly such as pulse width and amplitude. Moreover, higher voltage pulse can be achieved by increasing the number of LTD module.
