Abstract :
In many applications the chip-embedded core of miniature devices is a micro-structured planar spiral power transformer (MPST), and operational and electromagnetic compatibility are key issues to its sizing. Numerical simulation aided design may then be used to solve them. This paper presents mathematical models and numerical simulation results related to sizing the ferrite core, the lumped parameters of the MPST, and their sensitivity with respect to the core thickness (the spacing between the planar windings) and the magnetic permeability of the ferrite core. These outcomes may be of interest to the electrical design of the device that uses the MPST and in analyzing its electromagnetic compatibility with the interfering working environment. Finally, we address the high-frequency noise reduction in DC/DC flyback power sources with MPST.
