Chapter 2 Introduction to Semiconductor <strong>Electronic</strong>s − DiodesFigure 2.23. Model for Example 2.4 with SimPowerSystems blocksI 1 I 220 Ω 20 Ω 20 Ω0.3 V 1.3 V 2.3 VI 3I 41 KΩV outFigure 2.24. Piecewise linear equivalent circuit for Example 2.415 – 50V out + 65– 50V out + 115 – 50V out – V------------------------------------------------------------------------------------------------------------------------- out= 01000This value is not consistent with the value displayed in the model in Figure 2.23, so we perform thefollowing check:I 1 ≈( 0.3 – 1.3) ⁄ 20 ≈ – 50 mAI 2 ≈ ( 1.3 – 1.3) ⁄ 20 ≈ 0I 3 = ( 2.3 – 1.3) ⁄ 20 ≈ 50 mAI 4 = 1.3 ⁄ 1000 = 1.3 mAI 1 + I 2 + I 3 ≠ I 42−14<strong>Electronic</strong> <strong>Devices</strong> <strong>and</strong> <strong>Amplifier</strong> <strong>Circuits</strong> with MATLAB® / Simulink® / Sim<strong>Electronic</strong>s® Examples, Third EditionCopyright © Orchard Publications
