基于单端谐振逆变器及快速频率跟踪技术的等离子手术刀电外科发生器

In this article, an electrosurgical generator (ESG) for driving plasma scalpel is presented with zero voltage switching (ZVS) turn-on over a wide load impedance range based on a fast frequency tracking technology. The ESG consists of a single-ended resonant inverter utilizing the frequency tracking technology and an adjustable dc voltage source. A resonant circuit for a single-ended resonant inver...
