Study of the Power Distribution of Each Impedance in the Electrical Circuit of Ionized Gas Coagulation Equipment

摘要

Medical plasma equipment is categorized as electrical equipment for use in medical treatment. The characteristics of both low-energy ionized gas coagulation equipment (LE-IGCE) as a low-temperature plasma source and high-energy ionized gas coagulation equipment (HE-IGCE) as a high-temperature plasma source strongly depend on the structure of the plasma equipment and the operating conditions. In this paper, to ensure the electrical safety of both the LE-IGCE and the HE-IGCE, the output current and power of both types of equipment are measured, and the power distribution is evaluated for each impedance in the electrical circuit. The power required to produce plasma using the LE-IGCE corresponds to the real power of the power supply, and it is higher than that required by the HE-IGCE. However, ohmic heating in the human body caused by the LE-IGCE is much lower than that caused by the HE-IGCE.
