PSPICE files: basic model library and additional examples

Library of basic models (switch.lib). Includes models CCM1, CCM2, CCMDCM1, and other models. (updated 2/14/08). This version allows PSpice to converge 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.
 An older version of switch.lib employs an equivalent version of CCMDCM1 that converges more easily in LTspice
