Granted: 2003-12-01
Abstract: A warpage-preventing substrate is provided, wherein a plurality of first conductive traces and second conductive traces are respectively formed on a first surface and a second surface of a core layer of the substrate, each conductive trace having a terminal. A plurality of first non-functional traces and second non-functional traces are respectively formed on the first and second surfaces of the core layer at area free of the conductive traces.

Moreover, an insulating material is applied over the core layer to cover the conductive traces and non-functional traces but exposing the terminals of the conductive traces. By different-density arrangement of the first and second non-functional traces to allow stress balance, under temperature variation, the insulating material on the first surface of the core layer may have similar deformation to the insulating material on the second surface of the core layer, thereby assuring flatness of the substrate without being warped.

Title: Three phase rectifier circuit with virtual neutral
Inventor: LUBOMIRSKY VADIM
IPC: H02M7/06
Filed: 2002-10-14
Granted: 2004-04-11
Abstract: A rectifier circuit powers three power conversion modules using a three phase AC input without a neutral connection. First, second and third bridge rectifiers are connected to first, second and third phases of the three phase AC input and produce first, second and third rectified waveforms, respectively. A connection between the first, second and third bridge rectifiers forms a virtual neutral. Capacitors are connected across the bridge rectifies to filter the rectified waveforms and to create a DC rail voltage. The DC rail voltages feed power conversion modules. Two of the three power conversion modules remain powered at a decreased voltage level when the remaining power conversion module fails. Inductors are connected between the bridge rectifiers and the capacitors to further smooth the DC rail voltages and increase the power factor. Alternately, inductors are connected between the phases of the three phase AC input and the bridge rectifiers.
