ABSTRACT:
Systems and methods presented herein provide for the control of electrical energy discharge from an electrode. In this regard, a sensor detects electrical energy discharged from the electrode and generates an electronic signal representative of a detected electrical energy discharge. Such a sensor may detect an electric field and/or light from the electrical energy discharge. The sensor may generate the electronic signal therefrom for subsequent processing. Accordingly, the system also includes a controller communicatively coupled to the sensor to determine a spurious discharge of the electrical energy discharge from the electrode. The controller processes the electronic signal to control at least one characteristic (e.g., voltage) of the electrical energy provided to the electrode. The controller may change a voltage of the electrical energy to the electrode in response to determining a spurious discharge of the electrical energy discharged from the electrode.
