design. Magnetic materials and their operating flux levels are given in Chapter 2. The ac inductor like a transformer, must support the applied voltage, Vac. The number of turns is calculated from Faraday's Law, which states: 10' P, [turns] [10-7] KfB,,cfAc The inductance of an iron-core inductor, with an air gap, may be expressed as:

Basic principles The transformer may be considered as a simple two-wheel 'gearbox' for electrical voltage and current. The primary winding is analogous to the input shaft The secondary winding is analogous to the output shaft. In this comparison, current is equivalent to shaft speed and voltage to shaft torque. In a gearbox, mechanical power (speed multiplied by torque) is …
