Simulation package shows detailed capacitor behaviour in SMPSs
SpiCALCI simulation software is an engineering tool that calculates performance characteristics and parameters for its advanced switch mode power supply (SMPS) multilayer ceramic capacitors (MLCCs). SpiCALCI 10, which replaces the previous version, features all of the new SMPS MLCCs that AVX has recently introduced; an enhanced part selection process makes it easier to find a valid part, and the option to view and save the output information that is used to generate graphs.
SpiCalci10 software allows design engineers to predict critical operational parameters, such as: self-resonant frequency, ESR, ESL, and phase angle, for a given ambient temperature, temperature rise, and operational frequency. Designers can adjust the latter variables numerically, via a button slide, to model important capacitor characteristics, including: ripple current, ripple voltage, and internal temperature. The software also enables the creation of interactive graphs for further analysis of: ESR and impedance vs. frequency, temperature rise vs. current, maximum current vs. frequency, maximum ripple voltage vs. frequency, phase angle vs. frequency, and capacitance changes with DC bias. The numerical data can be imported to SPICE simulation software, and graphs may be saved and printed for presentation and/or sharing.
New additions to the SpiCALCI 10 product catalogue include: ST10, RT10, and SMX 25V rated parts; parts with voltage ratings spanning 25V to 5,000V; VHT (X7R) dielectric high temperature parts; the SV Series with N1500 dielectric; SXP Series parts rated for 1500V, 2000V, and 3000V; MIL-PRF-49470 T-Level BP (C0G /NP0) PS01 and PS02 style parts in case sizes 3, 4, 5 with 100V, 200V, and 500V voltage ratings; and MIL-PRF-49470 T-Level BX (X7R) 25V PS01 style parts in case sizes 1 – 6.
