Abstract: Cold plasma, recognized as the fourth state of matter, requires high voltage and high-frequency power sources tailored to the type of gas and intended application. This work presents the design and implementation of a 1000 Vp, 50 W Class E resonant power source operating at 24 kHz for generating cold plasma. The system was developed for applications such as biomedical sterilization and material treatment. The design incorporates a PWM-controlled driver, MOSFET-based Class E amplifier, and resonant tank, validated through both simulation and physical testing with helium and argon gases. Results demonstrate stable operation, adjustable frequency ranges from 5 kHz to 60 kHz, and effective plasma generation suitable for experimental and applied research in plasma-based technologies.

Keywords: High frequency, cold plasma, Class E amplifier, ionization, biomechanical applications
