Abstract
This circuit consists of the hi-voltage generator (HG) and the hi-voltage energy-storage capacitor (ESC). HG converts the main power into hi-voltage and applies to the hi-voltage apparatus (HA). ESC connects in parallel with HA. The special point is that a low-resistance discharging resistor (LDR), controlled by a relay, connects in parallel with ESC. When starting to supply the power to HA, the relay cuts off the LDR circuit. When stopping to supply the power to HA, the relay connects LDR with ESC. This circuit suits those non-handy, continuous working HAs. It raises the safety of using and maintaining these HAs. During auto discharging rapidly, the remaining hi-voltage of HA will not hurt the user. Even if people touch carelessly the open part of HA, there is no dangerous strong current though human body.
