The textbook is written by industry experts with practical experience in the field of electro-mechanical engineering.
It is a practical and user-friendly guide to design transformers and inductors. It presents a step-by-step approach, information, and guidance based on the needs and perspectives of the user. It is updated and expanded to reflect current industry trends. It continues to be an essential reference for anyone wanting to apply the latest state-of-the-art in transformer and inductor design.
The size and material of the wire used to make inductors and transformers can affect the inductance and fill-factor of the devices. Typically, inductors have a ferrite core. To calculate the amount of fill-factor, use a chart provided by Wikipedia. The size of the wire also affects the number of turns.
Besides power electronic converters, transformers and inductors play important roles in energy storage, filtering, and voltage-current transformation. This article covers some basic concepts and design considerations, but it is by no means comprehensive. Transformers are basically made up of two or more windings, which are magnetically coupled. They are often disposed on low-reluctance materials.
Integrated parallel matrix transformers and inductors can be constructed with multiple primary and secondary windings. This design allows for different turn ratios and configurations. The secondary windings can also overlap. This design also enables multiple transformers on a single PCB. The two devices may share the same primary winding.
Inductors are not without their downsides. They tend to lose energy through magnetic flux and eddy current losses. However, they can reduce the risk of eddy current leakage by placing the primary and secondary windings close together. Another design technique aimed at reducing magnetic flux leakage is to gap the center leg.
Transformers and inductors have similar design principles. The choice of the transformer and inductor can determine the amount of power, current, and frequency of the output. The size of the transformer is important as well as its expected loss. A large size of the inductor is not optimal for high-current or high-voltage applications.
An inductor is an electromechanical component that consists of two coils of insulated wires around an iron core. The primary coil is connected to an AC input source, while the secondary coil is connected to an independent electric circuit. The ratio of the primary to secondary windings determines which coil will produce the higher voltage. A higher ratio between the primary and secondary windings is referred to as a step-up transformer.
Inductors with a high inductance cannot be controlled precisely. Nevertheless, high inductance values are essential for DC/DC converters, which require large amounts of inductance.
