It will be noted that some figures have not just one, but instead two figure numbers for the effective circuits (for example, 300.1, 300.2 for FIG. 4A). The index numbers “n” (“300.n”) refer to the corresponding conversion modes in each case. So for FIG. 4A, the one set of switch settings 395 may result in either mode CM1 or CM2, depending on the choice of inputs/output terminals 302 (column 397 of Table Λ).
In FIGS. 4A-4D, solid circuit lines 410 (“![custom character]()
”) represent the actual current conducting paths that result from the illustrated switch settings. In the same figures, dotted circuit lines (“![custom character]()
”) 420 represent non-conducting paths, that is, circuit paths which are present on the A-PS 300 but are not conducting any current due to one or more open switches. (Note that in the case of inductors 355 (L1 and/or L2), an inductor 355 may be non-conducting if a switch arranged in parallel is closed; for example, if switch SW4 is closed, this may effectively shunt current around inductor L1.) In the figures, then, the dotted (non-current carrying) circuit lines 420 as shown for purposes of exposition and learning only, as they illustrate the circuit paths of exemplary A-PS 300 which are rendered null (non-conducting) for the conversion mode illustrated.
