用于电外科发生器系统的双频超宽负载谐振逆变器

This letter presents a dual-frequency electrosurgical generator (ESG) based on a Class EF inverter, designed to accommodate ultra-wide impedance variations encountered during surgical procedures. The inherent load-insensitive characteristics of the Class EF inverter at a single frequency are further enhanced through the adoption of a dual-frequency operation strategy. To explore the design potenti...
