Table 1 shows how to calculate inductance (L). The inductance is dependent on multiple factors, such as the number of turns, core dimensions, and permeability. The coil can be different shapes and sizes, and can be wound using different core materials. Inductors are formed using insulated wire wound as a coil. Figure 1 shows an inductor model.įigure 1: Electrical Model of an Inductor This means that if the current increases, the magnetic field increases. Inductors convert electrical energy into magnetic energy by storing, then supplying energy to the circuit to regulate current flow. What Is an Inductor?Īn inductor is a component in an electrical circuit that stores energy in its magnetic field. This article will provide guidance on how to select the optimal inductor for a solution while predicting the inductor’s performance when designing a new DC/DC converter. When selecting an inductor, it is important to understand the electrical characteristics noted in the inductor’s datasheet. Complexity arises when individual components are combined to create an inductor with the proper size, weight, temperature, frequency, and voltage to meet a target application. Inductors are relatively simple components, comprised of an insulated wire wound in a coil. It is essential to understand the electrical characteristics of inductors to design systems that are compact, cost-effective, efficient, and provide excellent thermal performance. These applications require power inductors mainly for battery-powered devices, embedded computing, and high-power/frequency DC/DC converters. Modern DC/DC converter demands are largely driven by consumer applications. Lattice Semiconductor Reference Designs.
