### PSPICE files: basic model library and additional examples

- Library of basic models (switch.lib). Includes models CCM1, CCM2, CCM-DCM1, and other models. (updated 2/14/08)
- SEPIC example of Section 2.4.3 (B.1.3.cir)
- Buck-boost example of Section 2.4.4
- switching circuit of Fig. 2.27 (B.1.4.switching.cir)
- averaged circuit of Fig. 2.28 (B.1.4.average.cir)
- SEPIC example of Section 2.4.6 (B.2.1.cir)
- Buck voltage regulator example of Section 2.4.7
- closed-loop circuit (B.2.2.closed-loop.cir)
- open-loop cirucit (B.2.2.open-loop.cir)

Update 2/14/08: the CCM-DCM1 model in switch.lib was updated to a new version that converges more easily in DCM and with dc operating point analyses. The model divides by zero at D = 0 (as does the earlier model when in DCM), but otherwise works well.
