Common-mode rejector for pulse power diagnostics
Abstract
Pulse power diagnostics are usually prone to common-mode noise pickup. A sure way of suppressing this noise is to introduce a common-mode rejector in each suspected signal line. Two types of rejector were developed. One handles signals with risetimes exceeding 10 ns, or equivalently with frequencies less than 35 MHz. The other is suitable even for signals with subnanosecond risetime. Both were optimized to yield the highest rejection achievable. The method of winding employed and the inter lead separation were found to be quite important for proper operation of the common-mode rejector. Some of the underlying mechanisms of ground noise generation are also briefly investigated.
