  1. Progress on the Klystron Modulators Chargers for CLIC Sklavounou Eleni TE – EPC – FPC

  2. Optimization Structure We are creating models to be integrated in a global optimization environment. Specifications and / or constraints Specifications and / or constraints

  3. Specifications and / or constraints • Objectives or constraints • Variables (topology selection and dimensioning) • Part of the global optimization Specifications and / or constraints

  4. Size of Charger and Capacitor Bank • Charger size: waiting offers from Heinzinger, Fug, Technix. • Capacitor size: AVX Film Capacitors

  5. Simulations If we want a constant charging power: Ideal charging current Very high bandwidth charger needed

  6. Simulations If we model the capacitor charger as a 2nd order transfer function:

  7. Simulations Result: Power fluctuation as a function of the bandwidth of the charger.

  8. Simulations • Now, we are studying a capacitor charger topology considering the internal capacitor as a second “filter”. • Which are the compromises between the internal capacitance and the bandwidth?

  9. Merci pour votre attention. At your disposal for any questions.
