SMPS Transformers

Switched-mode power supply (SMPS) transformers are a type of transformer used in power electronics to convert AC voltage to DC voltage with high efficiency. They are commonly used in applications such as computer power supplies, LED lighting, and motor drives.

The basic principle of an SMPS transformer is to use a high-frequency switching circuit to convert the input voltage to a high-frequency AC voltage, which is then rectified and filtered to produce the DC output voltage. The SMPS transformer is a critical component in the switching circuit, and is designed to handle high frequencies and high voltages without overheating or breaking down.

SMPS transformers are typically designed with a ferrite core, which has a high magnetic permeability and low magnetic losses at high frequencies. The core is usually in the form of a toroid, pot core, or E-core, and is wound with one or more coils to create the primary and secondary windings of the transformer.

The primary winding of the SMPS transformer is connected to the input AC voltage, while the secondary winding is connected to the rectifier and filter circuit, which produces the DC output voltage. The number of turns and the size of the wire used in the windings are determined by the required voltage transformation ratio and the frequency range of the circuit.
