STERILIZATION SYSTEM EMPLOYING A SWITCHING MODULE ADAPTED TOPULSATE THE LOW FREQUENCY POWER APPLIED TO A PLASMA |
摘要 |
A sterilization system and method applies low frequency power to a plasma within a vacuum chamber to remove gas or vapor species from an article. The sterilization system includes a switching module adapted to pulsate the low frequency power applied to the plasma and a low frequency power feedback control syste m for controllably adjusting the low frequency power applied to the plasma. A powe r monitor is adapted to produce a first signal indicative of the low frequency power applied to the plasma within the vacuum chamber. A power control module is adapted to produce a second signal in response to the first signal from the power monitor, and a power controller is adapted to adjust, in response to the second signal, the low frequency power applied to the plasma to maintain a substantially stable average low frequency power applied to the plasma while the article is being processed.
