Inductors and transformers are fundamental components in electrical engineering, playing crucial roles in various applications ranging from power supply circuits to signal processing. An inductor is a passive electrical component that stores energy in a magnetic field when electric current flows through it, while a transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. The importance of patents in the electrical industry cannot be overstated; they protect innovations, encourage research and development, and ultimately drive technological advancement. This article aims to explore the significant patents related to inductors and transformers, highlighting their historical context, key innovations, and future trends.
Inductance is the property of an electrical conductor that opposes a change in current. When the current through an inductor changes, the magnetic field around it also changes, inducing a voltage that opposes the change in current. This principle is fundamental to the operation of inductors and transformers, making them essential in various electrical applications.
