Abstract: A composite structure includes a first surface and a second surface sandwiched together with a field array of individual and discrete pillars extending therebetween. The plurality of discrete pillars each have a tailored coefficient of thermal expansion and are designed to expand and contract over varying temperatures. The discrete pillars are specifically arranged within the composite structure to compensate for the shrinkage and expansion of different components of a microelectronic hybrid device, to reduce thermal expansion induced deformations imparted on facets of the microelectronic hybrid device under varying temperatures.

Abstract: Methods and systems for bi-directional multi-port power conversion systems and applications are disclosed. In some sample embodiments, current-modulating power converters can be used to provide conversion between synchronous and asynchronous power. In some sample embodiments, current-modulating power converters can perform power conversion can be performed to and from three-phase AC with an active neutral line. In some sample embodiments, current-modulating power converters can convert between synchronous and asynchronous power and also support three-phase AC with active neutral.

Abstract: A car charging station in which battery buffering includes at least approximately as much energy as is required to charge one car rapidly. This is particularly advantageous when a photovoltaic array is connected through a power converter to charge the battery, and also to provide a lower rate of charge directly to the vehicle charge connections. Advantageously, a mains power connection can also be made through yet another port of the same multiport power converter.
