• Page 88: see attached corrected Table 4.3
• Page 232, line following Eq. (7.139): formatting of equation variables in text
• Page 235, Fig. 7.44 (b): (I1 + i1hat) is not the same as the inductor current, nor should the V1/(DD') dhat voltage source be in series with the inductor. Instead, both of these should appear in series with the transformer primary.
• Page 239, fifth line of text: "averaged" is misspelled.
• Page 242, text following Eq. (7.153): "to" and "equations" are misspelled.
• Page 243, middle of next-to-last paragraph: inductor resistance in Fig. 7.53 is RL = 0.1 Ohm
• Page 262, Problem 7.17(a): "account" is misspelled
• Page 327, caption to Fig. 8.71: "buck-boost converter"
• Page 395, line following Eq. (10.31): change "Cf" to "Cb"
• Page 406, Fig. 10.30: value of C is 100 uF, not 100 uH.
• Page 412, Fig. 11.3: at the beginning of the second period, the current i₂ should remain at zero, and the voltage v₂ should switch to (Vg - V).
• Page 423, Eq. (11.50): g2 = 2/(M*Re)
• Page 447, Fig. 12.10: vertical dashed line should pass through the peak of the perturbed current waveform
• Page 454, Eq. (12.43): should read Zout(s) = R2 || R || (1/sC)
• Page 458, Fig. 12.21: expression for ac resistor is inverted, and should read -R/D²
• Page 475, Fig. 12.31: at the beginning of the second period, the current i₂ should remain at zero.
• Page 536, Problems 13.6 and 13.7: change "Fig. 6.28" to "Fig. 6.27"
• Page 537, Problem 13.12: Isolated SEPIC schematic and waveforms are given in Figs. 6.37 and 6.38.
• Page 544, paragraph following Eq. (14.16): the exponents in the expressions for the resistivity of copper should read 10^-6
• Pages 561-562: Core loss density should be 0.04 W/cm^2, in Fig. 14.16, Eq. (14.90), and text above Eq. (14.90). This leads to total core loss of 0.25 W.
• Page 622, last line of text: change "current source i_s" to "current source i_r"
• Page 623, Eqs. (17.13) and (17.14): substitute i_r for i_R
• Page 655, Eq. (18.57): see attached correction to Eq. (18.57).
• Page 671, Eq. (18.98): v-hat and v_control-hat are interchanged.
• Page 806, Fig. A.4 waveform should be a sine wave
• Page 832, Fig. B.19: value of Epwm source should read: value={LIMIT(0.5*vx, 0.1, 0.9)}
• Page 836, Eq. (B.30) should read: Va = Rf ma Ts
