View A Transformer's Hysteresis Curve With An Ultra-Simple Circuit

摘要

A magnetic material's hysteresis curve is a powerful visual tool that can perform a graphic analysis of a transformer's behavior. Better-equipped laboratories employ a hysteresis graph to view the actual curve. However, unless serious magnetic work is being performed, the high-priced equipment needed for this approach is out of reach for most engineers. Sometimes a simple graphic representation is all that's required, and the circuit explained here can fit the bill.
