1. An electrosurgical controller comprising:
- a wand connector configured to couple to a connector of an electrosurgical wand, the wand connector comprising a plurality of electrical pins;
a voltage generator comprising;
a first transformer comprising a primary winding and a secondary winding, wherein the secondary winding defines a first terminal coupled to a first electrical pin of the plurality of electrical pins of the wand connector and a second terminal coupled to a second electrical pin of the plurality of electrical pins of the wand connector;
a second transformer, different than the first transformer, the second transformer comprises a first winding and a second winding, wherein the second winding of the second transformer is coupled to the secondary winding of the first transformer;
wherein the electrosurgical controller is configured to modify voltage of an alternating current (AC) signal induced on the secondary winding and applied to the first electrical pin relative to the second electrical pin by selective control of an impedance of the second winding of the second transformer.

Abstract
An electrosurgical controller with wave-shaping. At least some embodiments are methods including generating an alternating current (AC) voltage signal within an electrosurgical controller. The generating may be by inducing an intermediate AC voltage signal on a secondary winding of a first transformer, and wave-shaping the intermediate AC voltage signal by a second winding of a second transformer coupled to the first transformer, and thereby creating a final AC voltage signal. Thereafter, the method includes applying the final AC voltage signal to electrical pins of a connector configured to couple to an electrosurgical wand.
