Development of 10 kV cascaded pulse power supply based on magnetic isolation trigger

The cascaded pulse power supply with the magnetic isolation is used to solve the problem of floating power supply of each cascaded unit. Its structure is compact and the trigger mode is simple and reliable. Using the trigger mode of magnetic coupling isolation can increase the tail branch in each concatenation unit simply and conveniently, reduce greatly the falling edge of output high voltage pulse, and improve the adaptability of cascade type pulse power. In this paper, a kind of 10 kV cascaded pulse power supply is developed. The rated working voltage of each cascaded unit is 1 kV for a total of 10 units. The voltage regulation range is 0-10 kV, the operating frequency is 1-10 kHz, the pulse current is 0-20 A, and the pulse width is 5-30 s.
