Grid  Active power fluctuation  Maximum power  Voltage level PFS  Voltage droop  Precision (voltage reproducibility) Specifications and / or constraints Charger  Bandwidth  Charger (internal ) capacitor  Charger size  Cost  Efficiency  Power fluctuation  Objectives or constraints  Variables (topology selection and dimensioning)  Part of the global optimization

S IZE OF C HARGER AND C APACITOR B ANK Charger size: waiting offers from Heinzinger, Fug, Technix. Capacitor size: AVX Film Capacitors

S IMULATIONS If we want a constant charging power: Charging Current Ideal charging current Very high bandwidth charger needed

S IMULATIONS If we model the capacitor charger as a 2 nd order transfer function: Power Consumption

S IMULATIONS Result: Power fluctuation as a function of the bandwidth of the charger.

S IMULATIONS 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?
