In the second part of this two part series on inductance calculation techniques, approximation techniques and handbook methods are shown for air-core structures that do not easily lend themselves to closed-form solutions.
The design of the ac inductor requires the calculation of the volt-amp (VA) capability. In some applications the inductance is specified, and in others, the current is specified.
The formula for calculating the series total inductance is the same form as for calculating series resistances: When inductors are connected in parallel, the total inductance is less than any one of the parallel inductors’ inductances.
INDUCTANCE CALCULATIONS 1. INTRODUCTION In this chapter we will define inductance, calculate the low frequency induc-tance of several common configurations of conductors, and extend the results of our calculations to high frequency. Up until recently, the calculation of inductance has received relatively little

Inductor Derivation for the Core Geometry, Kg Introduction Inductors, like transformers, are designed for a given temperature rise. They can also be designed for a given regulation. The regulation and energy-handling ability of a core are related to two constants, Kg and Ke, by the equation: (Energy)2 = K gKea, [21-D1] Where: a = Regulation, [%]
Inductors in Series Equation. Ltotal= L1+ L2+ L3+ ….. + Lnetc. Then the total inductance of the series chain can be found by simply adding together the individual inductances of the inductors in series just like adding together resistors in series.
