Hysteresis loss calculation for Magnetic circuits in PSpice made easy

Calculating hysteresis loss becomes important while working with magnetic circuits.

As a result of magnetic hysteresis, energy is dissipated in the form of heat. This dissipated energy is proportional to the area of the magnetic hysteresis loop. The total area enclosed by the B-H loop is the measure of the hysteresis loss per unit volume per unit cycle.

PSpice has built-in Hysteresis Core Loss application that calculates the area of the B-H curve, which is the integrated average of B-H loops, on the basis of the specified time range, that is, the start time and end time.

If the specified time range covers more than 50 B-H loops, the area of the B-H curve is calculated using the first 50 B-H loops. If the specified time range covers less than 50 B-H loops, the area of the B-H curve is calculated using the number of the loops covered within the specified time range
