Abstract
A high frequency transformer is made on a magnetic circuit which can be of a generally square shape. The secondary windings are made on printed circuit plates, separated by insulators and traversed perpendicularly by the core or cores of the magnetic circuit. The primary winding can be wound directly on such a core. The transformer is applicable in particular to high frequency very high voltage power supplies, in particular of the type termed 'flyback' power supplies.
