A switched mode power supply (SMPS) is a more modern and efficient take on the older power supplies known as linear supplies. LINEAR SUPPLIES Linear supplies would often take in line voltage, transform this via a low-frequency silicon steel core transformer to a lower voltage. Then through rectification using diodes, and filtering using capacitors,…
AVOIDING CORE SATURATION
Lines of magnetic flux are created when a current flows through a conductor. They can transport energy from one winding to another usually though a permeable core of some kind. The amount of flux per area is known as flux density. Transformer and inductor cores have finite flux densities. That is, they can only handle so much flux over…
