Bias supply for plasma processing systems with periodic voltage application
The granted patent (Publication Number: US11887812B2) discloses a bias supply system that applies a periodic voltage through a series of components including inductors, switches, and a controller. The system involves an output node, a return node, and a switch connected to inductors and a voltage source to generate the periodic voltage. The controller is responsible for regulating the application of the periodic voltage by controlling the switch to allow the current to complete a full cycle from zero to peak value and back, ensuring the desired voltage output between the output and return nodes.
Furthermore, the patent details the controller's ability to adjust the voltage source and timing of switch closures to achieve the desired periodic voltage output. The controller, which can include a processor or a field programmable gate array, is equipped with a non-transitory computer-readable medium containing instructions for controlling the switch's operation. This configuration allows for precise control over the bias supply system, ensuring the accurate generation of the periodic voltage as needed for various applications.
