Title: RF output signal commutation in multi-channel electrosurgical unit
Keywords: Electrosurgery, power commutation

Abstract: This article reviews the existing problems with the output power commutation in electrosurgical units (ESU) in cases of multi-channel configuration, with requirement for high speed commutation rate between connectors, including in active mode. Attention is drawn to the methods for transmitting the output power to different outputs. A new type of output signal management based on the use of magnetic amplifiers is proposed. The proposed hardware solution is preliminary simulated and tested with PSpice A/D (Cadence product). The achieved results are analyzed and commented. Tests also are performed with physically realized device and the results are analyzed and evaluated in context of applicability in multi-channel ESU as well as in sterilization equipment.
