Abstract: A system and method for high voltage oscillation damping and capacitance controlling is provided. The system includes a high-voltage circuit including a first switching component and a second switching component connected in series and a layered bus system in electrical communication with the high-voltage circuit. The layered bus system includes alternating bus bar layers of an electrically insulative material and bus bar layers of a conductive material. The layers of the conductive material each comprise a first material and a second material, the second material having a higher resistivity than the first material. A geometry of the layers of the conductive material equalizes a capacitance across each of the first switching component and the second switching component.

Abstract: A method to provide power to a control supporting circuit includes connecting an optical power converter to the control support circuit, the optical power converter connected to a laser source via a fiber optic cable, controlling, by a controller, a laser source driver to drive a laser source providing a laser and the control supporting circuit; and supplying power to the control supporting circuit by irradiating the optical power converter with the laser via the fiber optic cable. A stray capacitance between the controller and the high voltage supporting circuit is reduced to zero or nearly zero. A method of shutting down a laser source driver providing laser energy to an optical power converter is also provided.
