  • High-voltage micro-ampere current regulator
    Patent number: 9958891
    Abstract: A high-voltage micro-ampere current regulator which can provide stable current regulation to a corona discharge without requiring a portion of that corona discharge to be sampled. The current regulator can optionally include a first feed-back circuit which provides rapidly-adapting current regulation, and an optional second feedback circuit which provides slowly-adapting current regulation to avoid changes in corona discharge due to oxidation of the corona emitter.
