Converter for connecting multiple AC voltage sources to a utility grid without first rectifying the AC to a common DC bus
Diodes and switching means as well as an autotransformer connect multiple AC sources of variable frequency and voltage to the utility grid, without first rectifying and thereby transferring the AC input energy to a common DC bus. Instead, the individual positive and negative AC input half waves or parts of those half waves, if and when they occur during a particular time interval, are injected into the positive or negative half wave of the utility AC power directly and respectively. The amount of energy transferred may be controlled by a microprocessor. Assuming the prime mover that generates AC voltages in multiple coils is a windmill, then the required circuitry to accomplish this energy transfer will be physically small enough to allow that circuitry to reside in the windmill itself, and thereby this energy conversion method significantly simplifies the installation of a windmill that uses this energy conversion method. |

Semiconductor structure having nanocrystalline core and nanocrystalline shell paring with compositional transition layer
Semiconductor structures having a nanocrystalline core and nanocrystalline shell pairing compositional transition layers are described. In an example, a semiconductor structure includes a nanocrystalline core composed of a first semiconductor material. A nanocrystalline shell composed of a second semiconductor material surrounds the nanocrystalline core. A compositional transition layer is disposed between, and in contact with, the nanocrystalline core and nanocrystalline shell and has a composition intermediate to the first and second semiconductor materials. In another example, a semiconductor structure includes a nanocrystalline core composed of a first semiconductor material. A nanocrystalline shell composed of a second semiconductor material surrounds the nanocrystalline core. A nanocrystalline outer shell surrounds the nanocrystalline shell and is composed of a third semiconductor material. A compositional transition layer is disposed between, and in contact with, the nanocrystalline shell and the nanocrystalline outer shell and has a composition intermediate to the second and third semiconductor materials. |
