Abstract
A magnetic and electrical circuit element including magnetic-flux-conducting posts, and a multi-layer structure formed with an electrically-conductive material. The multi-layer structure includes multiple layers forming a stack of layers along a length of the posts, said multi-layer structure configured as primary and secondary windings of a transformer. The primary winding is embedded in the multi-layer structure and wound around the magnetic-flux-conducting posts in such a way that a magnetic field induced in each of the magnetic-flux-conducting posts has a magnetic field polarity opposite to a polarity of the respective magnetic field of the magnetic-flux-conducting post adjacent the respective magnetic-flux-conducting post. Around each of the magnetic-flux-conducting posts, there is a respective one of the secondary windings connected to a semiconductor device. The magnetic-flux-conducting posts are connected magnetically by continuous magnetic-flux-conducting plates, each of which is shaped to ensure a continuous flow of the magnetic field successively through adjacent magnetic-flux-conducting posts.
