How To Minimize Core Saturation

Focus:
Saturation can be a limiting factor in the design of many magnetic components. Multiple component parameters such as core type (including material and geometry) and number of turns, as well as circuit parameters such as winding current and field current influence the degree of saturation seen in the application. Because the relationships among these parameters are not always obvious, determining the conditions required to minimize saturation can be challenging. In this article, the author provides an analysis of saturation that determines the optimum current waveform characteristics and number of turns required to minimize peak saturation for a given core type.
