1. A method for generating cold atmospheric plasma comprising:
generating electrical energy having a frequency less than 300 kHz with an electrosurgical generator, wherein step of generating electrical energy having a frequency less than 300 kHz comprises:
generating high frequency electrical energy having a first frequency and a first power;
converting with a resonant transformer said generated high frequency electrical energy at said first frequency and said first power to low frequency electrical energy having a second frequency lower than said first frequency and a second power lower than said first power;
wherein said first frequency is greater than or equal to 400 KHz and said second frequency is less than or equal to 300 KHz; and
controlling flow of an inert gas flowing through a cold atmospheric plasma probe and applying said electrical energy having a frequency below 300 kHz to said inert gas to produce a cold atmospheric plasma.
