Patent ID: 10603100

Abstract:
A controller for an electrosurgical device and related methods and devices are disclosed. The controller has a processing component to: (a) derive a power factor of power applied to the electrosurgical device; and (b) responsive to the deriving a power factor, assign a circuit status to a circuit comprising the electrosurgical device. IF (PF≈0) and ((Vrms/Irms)≥T), THEN the circuit status is “open”. IF (PF≈0) and ((Vrms/Irms)<T), THEN the circuit status is “short”. PF is the power factor. Vrms is the root mean square of a voltage associated with the power applied to the at electrosurgical device. Irms is the root mean square of a current associated with the power applied to the electrosurgical device. T is a threshold value.
