Abstract
A radiofrequency (RF) generator for use with an electrosurgical system includes a shifted, transformed LCLC bandpass filter, configured for allowing the RF generator to operate using a single electrosurgical power setting while preventing overheating of the electrosurgical system. The LCLC bandpass filter may be configured to operate with a specified power curve such that an operating current generated by the RF generator is folded back when approaching short circuit conditions. The RF generator may include a fixed, medical power supply, wherein the specified power curve is modified by switching frequency modulation of the LCLC bandpass filter. Further a method for designing a RF generator for electrosurgical application is disclosed.
