Abstract (en)
[origin: CN116547234A] The present disclosure describes systems and methods for controlling electrical generation of nitric oxide. In some aspects, a system for generating nitric oxide includes a plasma chamber containing two or more electrodes in communication with a resonant high voltage circuit configured to send a signal to the plasma chamber to generate nitric oxide in a product gas from a flow of reactant gas; and a controller configured to generate a pulse width modulated signal having a plurality of harmonic frequencies to excite the resonant high voltage circuit. The controller is configured to adjust a duty cycle of the pulse width modulation signal, the controller selecting the duty cycle based on a target voltage before plasma formation and a target current in the plasma chamber after plasma formation.
