Plasma discharging is a non-linear load whose impedance has large deviations, depending on the on/off state and size of discharge. The goal of the project was to provide reliable broadband, high-voltage, high-power power supply for unbalanced plasma discharging at atmospheric pressure.

The implemented power supply consists of a transistor amplifier and a transformer system with a ferrite core. The design of the system was performed by a combination of computer simulations and experiments. The output step-up broadband transformer is the new solution. The power supply covers the frequency range (10 – 700) kHz, the nominal power is 100 W, while the output voltage equals (0 – 5) kV. Power supply facilitates research and implementation of plasma discharge for the treatment of living organisms in medicine and agriculture.
