VOICE, DATA & VIDEO INTEGRATION: Active filter hardware design & performance for the DIII-D plasma control system

Summary: The digital plasma control system (PCS), currently in operation on the DIII-D tokamak, requires inputs from a large number of sensors. Due to the nature of the digitizers and the relative noisy environment from which these signal are derived, each of the 32 signals must be conditioned via an active filter. Two different types of filters, Chebyshev and Bessel with fixed frequencies: 100 Hz Bessel was used for filtering the motional Stark effect diagnostic data. 800 Hz Bessel was designed to filter plasma control data and 1200 Hz Chebyshev is used with closed loop control of choppers. The performance of the plasma control system is greatly influenced by how well the actual filter responses match the software model used in the control system algorithms. This paper addresses the various issues facing the designer in matching the electrical design with the theoretical.

In this letter, a minimized closed-loop dual-band filters using trisection stepped-impedance resonators (SIR) structure is presented. The closed-loop trisection SIR with dual-band frequency response are designed, and to establish appropriate couplings in the structure. Moreover, the proposed filter also provides the size reduction of the maximum 98% against the other dual-band filter. The total size of the filter is less than 14 mm × 14 mm based on RO3003 substrate. In addition, the proposed filter can be implemented by using a printed circuit board (PCB) technology to achieve low-cost, easily integrated design and fabrication. © 2006 Wiley Periodicals, Inc.
