Plasma scalpel driving power supply

The invention discloses a plasma scalpel driving power supply, which belongs to the technical field of plasma medical treatment and comprises an electronic voltage regulator, a rectifier module, an inverter module, a boost module, a step-down module, a control module, a driving module, a display module and a detection module. Driving signals are provided through the DDS signal generator, the highest working frequency can reach 4 MHz, plasma in a plasma thin layer close to the electrode obtains more energy, the number of high-energy particles is larger, the frequency of impacting the tissue surface is higher, the ablation rate is higher, and meanwhile under the high working frequency, the ablation rate is higher. The pulse polarity alternation can be completed within the cell polarization time, so that the electroporation effect caused by cell polarization is reduced, meanwhile, thermal damage and mechanical damage to tissue cells are reduced, the cell-level operation precision is achieved, and the device is w
