Plasma ignition generator with customizable voltage profiles
The patent US12074008B2 describes a generator designed for igniting plasma within a plasma chamber. Central to this invention is an ignition profile generator that includes a data interface for receiving voltage specifications as a function of time, an ignition data generator for creating an ignition profile, and a datastore for storing this profile. The generator also features a waveform generator that applies the ignition profile to its output. Additionally, the generator can identify an ignition voltage that is less than the maximum voltage of the plasma chamber, ensuring safe and effective ignition. The design incorporates a feedback module to refine the ignition process using test profiles that help determine the optimal ignition voltage.
Further details of the invention include the capability of the waveform generator to produce voltage waveforms through either a linear or switch-mode amplifier. The generator's functionality is enhanced by a non-transitory processor-readable medium that contains instructions for creating and applying the ignition profile. This medium allows for the reception of voltage and time values, which can be input by an operator or generated automatically. The instructions also facilitate the application of a changing voltage to identify the ignition voltage, ensuring that the resulting ignition waveform effectively transitions to and stabilizes around the ignition voltage. Overall, the patent outlines a sophisticated system for plasma ignition that emphasizes precision and adaptability in its operation.
