ABSTRACT:
A transformer and associated rectifier for supplying low voltage (e.g. 5 volts), high current (e.g. 1,500 amperes) power to a load such as a supercomputer, with a high electrical conversion efficiency and a high volumetric efficiency. The primary winding comprises a number of disc-shaped coils which are spaced apart from each other by coaxial single turn secondary coil elements which are interleaved between the primary coils. A core having E-shaped parts has an inner portion extending through the primary and secondary coils and an outer portion forming two windows with the inner portion, so that the coils extend through the windows. A rectifier assembly is mounted directly to plates which support and act as terminals to the secondary coils.
