提出了一种简单的低温脉冲功率解离高阻液体的方法。传统高压脉冲电源采用有源高压反弹尾脉冲二极管（RTP）。为了解释这一方法，研究采用了去离子水（DIW）（高电阻）电解与两个浸没电极。在电极上施加的正向脉冲为全宽为400 ns，正向电压为7 kV，上升比为1011V/s。在该电路中简单采用5kv RTP二极管和DIW负载串联时，在该电路中施加正向高压脉冲和连续的反向大电流。然后在阳极电极生成h2o2，在水容器中生成OH自由基（OH）。这些现象明显与阳极电极面积有关。在前向高压应用开始时，电路表现为电容负载，产生离子并在DIW和电极之间的界面处建立电荷。连续反弹的高反向电压和高度堆积的反向恢复电荷引起RTP二极管的雪崩击穿。发现回弹电流在电路中被收集，伴随着氢和OH的产生，以及在界面处流动的尾电流作为阻性负载。因此，我们指出，根据电路中插入的rtp二极管，从周围水注入到阳极电极界面的回弹电子诱发了典型的水电解。
Simple low-temperature pulsed power dissociation method for high resistive liquid is proposed in this article. Active high voltage rebound tailing pulse (RTP) diodes are adopted to conventional high voltage pulse power sources. In order to explain this method, the study was performed using deionized water (DIW) (high resistivecm) electrolysis with two immersed electrodes. The forward pulses, the full-width at half-maximum (FWHM) of 400 ns and forward voltage (7 kV) with rising-up ratio (dV/dt) of 1011V/s, were applied to the electrodes. When a 5 kV RTP diode was simply adopted to this electrical circuit and DIW load in series, the high forward voltage pulse and continuous high reverse current were applied to this circuit. Then, H2was generated at the anode electrode and OH radical (OH) in the water vessel. Those phenomena were apparently dependent on the anode electrode area. At the beginning of the forwarded high voltage application, the circuit behaved as capacitance load with generated ions and built up charges at the interface between DIW and the electrode. Continuous rebounded high reverse voltage and highly built-up reverse recovery charges induce avalanche breakdown of RTP diode. The rebounded electrical current was found to be collected in the circuit, accompanied by the generation of hydrogen and OH, as well as the tailing current flowing at the interface as a resistive load. In consequence, we point out that rebounded electrons injected from the surrounding water to the anode electrode interface induced the water electrolysis characteristically, according to RTP-diode inserted in the circuit.
