This paper gives out the principles and improving schemes of transformer discharge equipment and resonance booster discharge equipment. By detecting the current in the main circuit, the gap's breaking-down can be identified, and the single chip micro-computer will send out corresponding control signal to make the IGBTs to switch off or cut off the input voltage, by this mean, we can make sure that every time of the experiment, the sample will discharge only once. The paper also introduces the principle of the protection circuit. At last, the experimental waveforms were listed, which prove the feasibility of the high voltage discharge fast switch-off device.
