The described system is an advanced cold plasma device, primarily designed for generating cold plasma at a temperature range of 65 to 120 degrees Fahrenheit. It includes a high voltage power supply system, which comprises a capacitor charging power supply, a capacitor bank, and a controllable switch like a silicon controlled rectifier (SCR). This setup is connected to a double-tuned RF transformer resonating at two distinct frequencies. The operation involves charging the capacitors, transferring energy through the controllable switch to the transformer, thereby generating a harmonic-rich output voltage for the cold plasma device. The system’s functionality is managed and adjusted through a controller, allowing for precise control over output voltage and frequency..
