SST High-Frequency Isolated Transformer Core Design and Calculation Material Characteristics Impact:Core material exhibits varying loss behavior under different temperatures, frequencies, and flux densities. These characteristics form the foundation of overall core loss and require precise understanding of nonlinear properties. Stray Magnetic Field Interference:High-frequency stray magnetic fields around windings can induce additional core losses. If not properly managed, these parasitic losses

I. Core Innovation: A Dual Revolution in Materials and StructureTwo key innovations:Material Innovation: Amorphous AlloyWhat it is: A metallic material formed by ultra-rapid solidification, featuring a disordered, non-crystalline atomic structure.Key Advantage: Extremely low core loss (no-load loss), which is 60%–80% lower than that of traditional silicon steel transformers.Why it matters: No-load loss occurs continuously, 24/7, throughout a transformer’s lifecycle. For transformers with low loa

The use of power electronics in industry is increasing, ranging from small-scale applications such as chargers for batteries and LED drivers, to large-scale applications like photovoltaic (PV) systems and electric vehicles. Typically, a power system consists of three parts: power plants, transmission systems, and distribution systems. Traditionally, low-frequency transformers are used for two purposes: electrical isolation and voltage matching. However, 50-/60-Hz transformers are bulky and heavy
