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.

Abstract: An ultrasonic motion generator includes a non-resonant inverter, an ultrasonic transducer, and a comparator. The non-resonant inverter inverts direct current (DC) to alternating current (AC) having a first frequency. The ultrasonic transducer is electrically coupled with the non-resonant inverter and generates an ultrasonic motion based on the inverted AC. The comparator automatically detects a deviation of the first frequency from a resonant frequency of the ultrasonic transducer based on motion current passing through the ultrasonic transducer and generates an output signal based on the deviation to drive the non-resonant inverter.
