The plasma scalpel power supply control system comprises an active grid-connected rectifying unit, a full-digital full-bridge LLC unit, a low-frequency voltage stabilizing circuit, an envelope line generating circuit, a high-frequency three-level H-type inverter bridge parallel group, a high-frequency high-voltage transformer and an FPGA software module which are connected in sequence. The FPGA software module is respectively connected with the active grid-connected rectifying unit, the full-digital full-bridge LLC unit, the low-frequency voltage stabilizing circuit, the envelope line generating circuit, the high-frequency three-level H-type inverter bridge parallel group and the high-frequency high-voltage transformer. Compared with a traditional power supply, isolation and safety are fully considered, and particularly, the absolute safety of a human body is fully ensured due to the addition of a capacitor charging and discharging link; besides, the working frequency can be improved from ...
