Errors can be reported for inclusion on this list by sending email to Bob Erickson. Please include page number and a short description. The errors listed below were corrected in the fifth printing.

• Page 84, eighth line of text:
  should read "... and hence the collector current decreases."
• Page 158, top line of text:
  D greater than or equal to 0.5 should read D less than 0.5
• Page 176, Eq. (6.63)
  "1 +" is missing in denominator, should be consistent with Eq. (5.28).
• Page 198, Eq. (7.31)
  Last line of equation: replace vg-hat with ig-hat
• Page 291, Eq. (8.91) is incorrect. See attached pdf file for corrected page.
• Page 307, first line of text should refer to Eq. (8.148) rather than (8.147):
  "Substitution of Eq. (8.146) into Eq. (8.148) leads to"
• Page 350, line following Eq. (9.35):
  where theta = -Gc ... minus sign should be angle symbol
• Page 363, third line of text:
  "... dependent voltage source G₁v_e": change ve to v-hat-e
• Page 380
  Units of vertical magnitude axis in Fig. 10.4 are dBV, not dB. In 10th line of text, "feedback" is misspelled.
• Page 390, Fig. 10.15, and Page 393, Fig. 10.19
  Units of vertical magnitude axes are dBV, not dB
• p. 443, last paragraph:
  "Likewise, the difference between the two waveforms is a constant iLhat(Ts) over the interval (D + dhat)Ts < t < Ts, since both waveforms then have the slope -m2."
  • the interval should start at DTs, not (D + dhat)Ts
  • single headed as opposed to the double headed arrows used could help with Figs. 12.4, 12.5 and the signs.
• Page 479, last sentence of first paragraph:
  Change "have" to "having"
• Page 498, line of text following Eq. (13.22):
  Replace "B = F/Ac" with "B = phi/Ac"
• Page 501ff:
  The core reluctance is listed as R_c in Fig. 13.14, but simply as R in Eq. (13.34) and following references. Subscript "c" should be added for consistency.
• Page 501, Fig. 13.14:
  Caption text should refer to Fig. 13.13.
• Page 541 to 542, Equations (14.35) and (14.36):
  Limits of summation should read j = 1 to k, consistent with Eq. (14.34)
• Page 553 to 554:
  Numbering of steps in design procedure: repeated 3
• Page 561, Eq. (14.88):
  Missing factor of 2 in denominator
• Page 716, Fig. 19.16, plot of || H ||:
  Qe = R0/Re (Same as in Zi plot)
• Page 734, third paragraph, eighth and ninth sentences (beginning "For f0 < fs < finf ..."):
  Eighth sentence should read: "For f0 < fs < fm, ..." and the ninth sentence should read: "This implies that zero-voltage switching is obtained under short-circuit conditions, and zero-current switching is obtained under open-circuit conditions."
• Page 738, Eq. (19.64):
  The correct value of I_mat is 0.196 A.
• Page 739:
  Eq. (19.67) is missing an equal sign, in front of the fraction.
  In Eq. (19.69), the correct value of X_p is - 1499 Ohms.
