The highvoltage supply widely applies in application domains and so on crude oil electric dehydration, material modification, metal smelting, environmental protection, high efficiency laser and microwave, the power frequency power source which and L the tradition high-voltage power supply uses the C resonance way, although the electric circuit is simple, but its volume and the weight are big, the low frequency active status as well as the ripple, the stability cannot be satisfying. The electric power electronics's swift development and switching power supply's use, causes the power source high frequency to turn into for the tendency, and in overseas had the fast development, domestic now as before by power frequency high-voltage power supply primarily, the highvoltage supply is not mature, for this reason, it is necessary to carry out the high frequency high-pressured high efficiency switching power supply's development. This article mainly introduced the IGB T application electric circuit, with, when has the disruptive discharge IGB the T electric current's limit and the protection circuit, realize the high frequency high-pressured pulse power source's overall design. The switch is in the pulse power equipment's key component, the pulse power equipment's performance the switch performance restriction, like working voltage, summit current, operating frequency, life and so on. At present in the high frequency high-pressured pulse power source charge system, the semiconductor switch component's overflow and has pressed the question serious influence entire electrical power system's efficiency and the stability.
key word: The high frequency high pressure, IGB T inverts, pulse power source soft switch IGBT, switch, stability
