The present invention provides an apparatus and method for generating an electric discharge in a liquid using a gas jet, in which a gas channel is formed between conductive members in a liquid using high pressure gas jet injection to reduce a discharge voltage in the liquid to a level similar to that in air, thus facilitating the electric discharge in the liquid. According to the present invention, a gas jet is repeatedly or periodically injected by controlling the opening and closing time of a pneumatic valve while a high voltage is applied, and thus the pneumatic valve serves as a high voltage pulse switch, which makes it possible to generate an electric discharge in a liquid without the use of the expensive high voltage pulse switch (or pulse power supply unit) Therefore, it is possible to reduce the capacity of the power supply unit for generating the discharge voltage and the manufacturing cost of the apparatus and increase the durability of the conductive members where a spark is generated during discharge. |
