Abstract: Aim The aim of this work is to design a GaN-based high -frequency full -bridge class DE resonant inverter topology for electrosurgery. Design & Methodology High -frequency and wide load range are taken into consideration in the design procedure. The selected switching frequency is 500 kHz. Variable loads are applied to the designed inverter and measurements are taken. . Originality In this study, a high -frequency full -bridge class DE resonant inverter operating in a wide load range for three modes of electrosurgery applications is designed. Findings The presented design is verified on a prototype and results are obtained for all three modes, pure cutting, blend, and coagulation, at variable loads. In addition, studies have been carried out on a different load simulating real tissue for all three modes. Conclusion A high -frequency inverter design operating at wide load range has been obtained for electrosurgery. On the potato load for pure cutting mode, an output voltage of 39.9 V and an output current of 0.7 A while the efficiency is around 35%.
