Abstract
A control device for a frequency generator of an ion thruster is described. The control device permits the detection of zero-crossings in a current and/or voltage characteristic during specific time intervals only, which detection is inhibited during other time intervals. Any incorrect switching performance of the control device associated with erroneously detected zero-crossings is prevented accordingly. A low-pass filter filters harmonics out of the detected current and/or voltage characteristics. A time-delay element offsets stray delays in the detection of zero-crossings. Additionally, plasma energy protective apparatuses are described, which attenuate the impact of any power flashover from a thruster unit to a power supply unit of an ion thruster.
