摘要： A stacked switched capacitor (SSC) energy buffer circuit includes a switching network and a plurality of energy storage capacitors. The switching network need operate at only a relatively low switching frequency and can take advantage of soft charging of the energy storage capacitors to reduce loss. Thus, efficiency of the SSC energy buffer circuit can be extremely high compared with the efficiency of other energy buffer circuits. Since circuits utilizing the SSC energy buffer architecture need not utilize electrolytic capacitors, circuits utilizing the SSC energy buffer architecture overcome limitations of energy buffers utilizing electrolytic capacitors. Circuits utilizing the SSC energy buffer architecture (without electrolytic capacitors) can achieve an effective energy density characteristic comparable to energy buffers utilizing electrolytic capacitors. The SSC energy buffer architecture exhibits losses that scale with the amount of energy buffered, such that a relatively high efficiency can be achieved across a desired operating range.

摘要翻译：层叠开关电容器（SSC）能量缓冲电路包括开关网络和多个储能电容器。开关网络只需要相对低的开关频率工作，并且可以利用储能电容器的软充电来减少损耗。因此，与其他能量缓冲电路的效率相比，SSC能量缓冲电路的效率可以非常高。由于使用SSC能量缓冲结构的电路不需要利用电解电容器，所以利用SSC能量缓冲架构的电路克服了利用电解电容器的能量缓冲器的局限性。利用SSC能量缓冲架构（无电解电容器）的电路可实现与使用电解电容器的能量缓冲器相当的有效能量密度特性。 SSC能量缓冲结构表现出随着能量缓冲量的增加而降低的损耗，使得能够在期望的工作范围内实现相对较高的效率。

摘要： An apparatus for generating electromagnetic radiation in which the radiation has both a first and second utility. The electromagnetic radiation is modulated to produce electronically detectable variations to achieve the second utility, the variations not affecting the first utility. In one embodiment, the electromagnetic radiation is visible light. In this embodiment, the first utility is illumination and the second utility is the transmission of data. In another embodiment, the invention provides a lamp for generating visible light capable of providing illumination and transmitting data to a receiver. Any variations in the visible light resulting from the data transmission are imperceptible by a human eye regardless of the nature of the data being transmitted. In yet another embodiment, a power line carrier modem may be used with the present invention to transmit information to the source.

摘要： A large signal, linear, digital, unity power-factor controller for controlling a power supply is disclosed. The power supply controller includes a voltage controller and a current controller. The voltage controller is a feed forward and proportional-integral type of controller. By determining the control command of the voltage controller as a function of the feed forward load power, the power term in the state equations for the voltage controller is eliminated. As such, the current controller operates in time domain in such a way that the voltage controller appears as a unit time delay to the current controller. The load is a battery incorporated within an electrically-powered vehicle. The controller operates to charge the battery. The connection between the battery and the power supply being controlled is an inductive coupling.
