1. An electrosurgical system comprising:
an electrosurgical instrument comprising:
a first jaw comprising a first electrode; and
a second jaw opposing the first jaw and comprising a second electrode, the first and second jaws pivotably arranged to grasp tissue between the first and second jaws and the first and second electrodes of the first and second jaws being arranged to transmit radio frequency energy (RF) between the first and second electrodes;
an electrosurgical generator arranged to supply the radio frequency (RF) energy, the electrosurgical generator comprising a controller arranged to periodically monitor a phase angle of the supplied RF energy and configured to signal an RF amplifier to increase voltage of the supplied RF energy when the monitored phase angle is greater than zero and increasing.
