Zusammenfassung:To provide a discharge technique of a high voltage pulse which contributes to reduce a discharge period.SOLUTION: A discharge device 10 comprises: a voltage rising circuit 11 that rises an input voltage Vfrom a power supply; a first capacitor C1 charged by a voltage to be risen; a second capacitor C2 which is parallely connected to the first capacitor C1 with a resistor R connected in series; a transformer 12 in which a primary coil L1 is connected to the second capacitor C2; a switching element 15 flowing a charge charged to at least the second capacitor C2 in which a close circuit is formed by the input of a trigger signal Sto the primary coil L1; and main electrodes 16 (16a and 16b) discharging a high voltage pulse 17 induced to a secondary coil L2 of the transformer 12.SELECTED DRAWING: Figure 1 【課題】放電周期の短縮化に資する高電圧パルスの放電技術を提供する。【解決手段】放電装置10は、電源からの入力電圧Vinを昇圧する昇圧回路11と、この昇圧された電圧により充電される第1コンデンサC1と、直列接続する抵抗器Rとともに第1コンデンサC1に並列接続する第2コンデンサC2と、この第2コンデンサC2に1次コイルL1が接続される変圧器12と、トリガ信号Sinの入力により閉回路が形成されると少なくとも第2コンデンサC2に充電された電荷を一次コイルL1に流すスイッチング素子15と、変圧器12の二次コイルL2に誘導された高電圧パルス17を放電する主電極16(16a,16b)と、を備えている。【選択図】 図1
