1. An electrosurgical controller comprising:
- a wand connector disposed on an outer surface of the electrosurgical controller, the wand connector configured to couple to a connector of an electrosurgical wand, and the wand connector comprising a plurality of electrical pins;
a voltage generator comprising;
an alternating current (AC) to direct current (DC) (AC-to-DC) conversion circuit;
a primary winding of a transformer coupled to the AC-to-DC conversion circuit; and
a secondary winding of the transformer, the secondary winding defines a first active terminal coupled to a first electrical pin of the wand connector and a second active terminal coupled to a second electrical pin of the wand connector;
the electrosurgical controller is configured to simultaneously provide radio frequency (RF) energy having a first voltage to the first electrical pin and RF energy having a second voltage to the second electrical pin, wherein the first voltage is higher than the second voltage.

Abstract
An electrosurgical controller with output RF energy control. At least some of the illustrative embodiments are electrosurgical controllers configured to change a first output voltage on the first active terminal relative to the first return terminal by selective control of a number of turns of the primary winding of a transformer used to create the output voltage.
