"LOOP" INDUCTANCE VS. “PARTIAL” INDUCTANCE
In the preceding chapters we have detailed the concept and calculation of “loop” inductance and “partial” inductance for various current-carrying structures consisting of conductors of circular, cylindrical cross section (wires), as well as conductors of rectangular cross section (PCB lands). In this final chapter we summarize the advantages and disadvantages of characterizing these structures with “loop” inductance or with “partial” inductance and give examples of the applications of partial inductance.
7.1 LOOP INDUCTANCE VS. PARTIAL INDUCTANCE: INTENTIONAL INDUCTORS VS. NONINTENTIONAL INDUCTORS
An important question that this book intends to resolve is: When should loop inductance be used to characterize a current-carrying, conductive structure, and when should partial inductance be used? A related question to be answered is: What are the advantages and disadvantages of loop inductance vs. partial inductance? There exists considerable misunderstanding throughout the electrical engineering community regarding “partial” inductance and where it is appropriate to use the concept to characterize the inductance effects of current-carrying structures. “Loop” inductance is a standard topic in undergraduate electrical engineering textbooks, but these textbooks do not contain any reference to “partial” inductance. Hence, electrical engineers are well trained in the understanding and calculation of loop inductance, but they have little or no ...
