Circuit conducting paths and topology: For convenience, and for identification in the presently appended claims and/or any claims which may be presented in the future with reference to this document, circuit nodes (connection points and/or branching points) have been labelled as N1, . . . , N32 (or generally as Ni, i=1, . . . , 32). It will be understood that the circuit paths 340 and circuit nodes Ni shown in the figure identify the circuit topology of the exemplary A-PS 300, and so constitute an exemplary description of the circuit. It will be seen, by way of a first example, that switch SW4 is connected between nodes N17 and N19, and that switch SW6 is connected between nodes N19 and N21, thereby electrically connecting switches SW4 and SW6 in series between nodes N17 and N21. By way of a second example, it will be apparent from the figure that inductor L1 and switch SW4 are connected in parallel between nodes N17 and N19, so that the state of switch SW4 being open or being closed may determine, in part, if current flows through inductor L1 or is shunted/short-circuited around inductor L1.
Similar identifications or characterizations for element connections and elements interactions, based on element connections to specific nodes, may be made for other circuit elements of exemplary A-PS 300.
