    Study Notes

    Chopper Quadrantes

    • Chopper quadrantorum duo typi sunt: secundus quadrantum chopper et primus et secundus quadrantum chopper.

    Secundus Quadrantum Chopper

    • Produit voltages positivas et currents negativas.
    • Voltages output (Vo) = (1 - x2) * Vi.
    • Voltages output DC (Vo,dc) = (1 - d2) * Vi.
    • Ratio efficaciae (M) = (1 - d2).
    • Currents output DC (Io,dc) = Vo,dc / R.
    • Uti negativity currents Io,dc, Vo,dc < E.
    • Limites ratio efficaciae: 1 - d2 < E / Vi et 1 - d2 < 1.

    Exemplum 1

    • Analysus secundus quadrantum chopper: Vi = 100V, E = 80V, d2 = 0.25, R = 10Ω, L = 20mH, fsw = 2kHz.
    • Calculus ratio efficaciae: d2 = 0.25.

    Exemplum 2

    • Calculus ratio efficaciae: Io,dc = -3A → Vo,dc = 50V → M = 0.25 → d2 = 0.75.

    Chopper Primus et Secundus Quadrantum

    • Produit currents bidirectionalis.
    • Chopper est combinatio primus et secundus quadrantum chopper.
    • x1 et x2 sunt variables switching S1 et S2.

    Chopper Primus et Quartus Quadrantum

    • Produit voltages positivas et negativas cum currents positivas.
    • Load emf (E) est positivus pro operationem primus-quadrant et negativus pro operationem quartus-quadrant.
    • Status chopper est designatus ut (x1x4)2, ubi x1 et x4 denotant variables switching S1 et S4.
    • Pro operationem primus-quadrant, switch S4 remanet on ut provideat pathem currents output.
    • Switch S1 performit chopping, cum ratio efficaciae d1, ita chopper operatur alternative in statu 1 (01) et 3 (11).
