TL;DR: In this article, a power conversion system includes a controller to provide power control to a converter, and a distortion mitigation circuit, where the controller may selectively disable the power control in response to a sense signal from the power path.
Abstract: In one embodiment, a power conversion system includes a controller to provide power control to a converter, and a distortion mitigation circuit. In another embodiment, a system includes a converter to transfer power between a power source and a load having fluctuating power demand, and a controller to provide power control, where the controller may selectively disable the power control. In another embodiment, a power conversion system includes a controller to generate a drive signal to provide power control to a power path in response to a sense signal from the power path, where the sense signal is taken from other than the input of the power path, or the drive signal is applied to the power path at other than a first power stage.

TL;DR: The use of contours for visualizing power system voltage data is discussed, and because of the low computation requirements of the contouring algorithm, the algorithm is implemented into a real-time animation of the voltage profile of a power system.
Abstract: Power system engineers are presented with vast amounts of information to analyze during daily operations. In systems containing thousands of buses, it can be very difficult to assess the state of the power system in an intuitive and rapid manner. The paper discusses the use of contours for visualizing power system voltage data. Also, because of the low computation requirements of the contouring algorithm, the algorithm is implemented into a real-time animation of the voltage profile of a power system. The contouring routines are implemented into the PowerWorld/sup TM/ Simulator software package, with results shown for systems with up to several thousand buses. Experiments and interviews with system engineers are also discussed to measure the applicability of voltage contouring as an add-on to practical EMS systems.

TL;DR: In this article, the authors consider the fact that almost all of the critical payloads in the data center are DC loads, and they propose a power distribution scheme for data center networks.
Abstract: The debate on the use of Direct Current (DC) as a power distribution means has been raging for decades. Recently, one focus of the discussion has been the data center. For various reasons, AC remains the preferred method of power distribution in the data center, despite some disadvantages inherent to AC power. This is particularly interesting when one considers the fact that almost all of the critical payloads in the data center are DC loads.
