Abstract

La presente invención coloca el arrollamiento primario de un transformador en una configuración donde rodea sustancialmente el arrollamiento secundario del transformador a fin de mejorar la eficiencia del acoplamiento electromagnético. El material de alta permeabilidad magnética rodea porciones del arrollamiento primario del transformador está diseñado para operar eficientemente a frecuencias de aproximadamente 50 kHz. En una forma de realización preferida, el arrollamiento primario de la invención es formado de dos formas de U en las cuales los miembros paralelos de la U son sustancialmente mas largos que la porción inferior de la U. Las dos formas de U forman una forma rectangular y las porciones rectangulares sustancialmente paralelas son rodeadas por material de alta permeabilidad magnética para mejorar adicionalmente el acoplamiento electromagnético entre el arrollamiento de bobina primario y el arrollamiento de bobina secundario. En otra forma de realización, el arrollamiento primario de la invención puede ser de forma rectangular. Un arreglo de línea de tira de la salida del secundario es formado de capas conductoras y aislantes laminadas conjuntamente. Una barra conectora de energía es configurada para tener una inductancia distribuída y se forma de dos conductores planos para crear una capacitancia distribuída que cancela sustancialmente el efecto de al inductancia distribuída.The present invention places the primary winding of a transformer in a configuration where it substantially surrounds the secondary winding of the transformer in order to improve the efficiency of the electromagnetic coupling. The high magnetic permeability material surrounds portions of the transformer primary winding is designed to operate efficiently at frequencies of approximately 50 kHz. In a preferred embodiment, the primary winding of the invention is formed of two U-shapes in which the parallel members of the U are substantially longer than the bottom portion of the U. The two U-shapes form a rectangular shape. and the substantially parallel rectangular portions are surrounded by high magnetic permeability material to further improve the electromagnetic coupling between the primary coil winding and the secondary coil winding. In another embodiment, the primary winding of the invention may be rectangular in shape. A strip line arrangement of the secondary outlet is formed of conductive and insulating layers laminated together. A power connector bar is configured to have a distributed inductance and is formed of two flat conductors to create a distributed capacitance that substantially cancels the effect of the distributed inductance.
