A Universal Simulated Power Inductor

Dr. Ramaswamy is back with another usefull piece of lab equipment. Imagine a box with two connections where you can 'dial in' any inductance between 10mH and 10H for your filter and cross-over trials. Fully floating of course and able to handle up to 1A signal current. This article describes the design and design choices made, and has the necessary info to build your own unit.
