With the development of pulse power technology and the application, power supply characteristics such as high repetitive frequency, high discharging precision and integrated pulse power supply with power semiconductor devices are highly required. Under the background, the technique of Marx pulse power supply based on thyristor is investigated in this paper.The development of Marx generator is introduced and the research of general and key technology is summarized. Based on circuit principles and simulation method, the resistor isolated Marx generator is analyzed from charging and discharging process, design of the Marx circuit and principle of critical devices choice. In this paper, an improved structure of resistor isolated Marx generator which can effectively avoid the prepulse on the load is proposed, the formulae of choosing balance charging resistors are deduced, and the MATLAB simulation of charging and discharging characteristics are shown.In order to improve the operating efficiency and repetition operating frequency, the whole inductor isolated Marx generator is designed and simulated, with the advantage and design principle analyzed. The hardware and software of the Marx generator above mainly base on the embedded controller, ICOP-6054VE and the multifunction data acquisition card, PM511P. Through the pulse triggering control of voltage adjusting module, the amplitude limited charging current and the charging voltage are controlled in the way of given parameter.With the growing requirement of high repetitive frequency, high charging precision and integrated pulse power supply, the research of Marx generator based on thyristor in this paper have some reference value for the design and application of this kind power supply.
