Research Based On MOSFETs Of In Series

Pulsed power technology is a new technology which came out with the development of power weapons, environment protecting technology and biology technology. It is the basic of many high-tech and the investigate hotspot of many countries. With the development of this technology, it's application areas are more and more abroad. The evolution of pulsed power technology has largely relied on the improvement of the switching units. For most pulsed power generators, the output power level, the repetition rate, and the output pulse shape usually depend on the performance of the switching units. But by the present manufacture technology. There be none new single units. But by the present manufacture technology. There be none new single unit can satisfy both the voltage level in topology and the speed level in drive technology is key factor in the development of the pulsed power technology.In this paper, the general high voltage pulsed power supply are analyzed and compared. A novel topology of high voltage fast front pulsed edge power supply which is based on the in series of power MOSFETs is proposed. The MOSFET is driven by UCC27321, by optical transmitters been triggered in series synchronously, the problem of synchronization is solved. Theoretically circuits design and PSpice simulation had been performed on these technologies, and the primary components had been selected based on these works. A experiment circuit has been build to study these technologies. The experiments show that MOSFET switch can work on series link of a small quantity of MOSFET can get higher switch voltage,but not affect too mach to the high voltage pulsed edge.
