Abstract: Systems and methods improve the forecast of electricity consumption, and/or refining such predictions. Predictions may be refined by accounting for factors such as preliminary predictions, pricing and cost information associated with future supply of energy, the extent of anticipated changes in the predictions, the time of day and/or anticipated daylight for the period of time. Coefficient values are calculated for a forecast error model that takes into account factors related to electricity consumption using existing historical electrical grid data. Using the calculated values, the forecast error model may be applied to current electricity demand forecasts.

Abstract: A method for operation of a single-ended forward converter to achieve “true soft switching” The method includes injecting, with a current source and in transformer winding, a narrow pulse of current via an injection winding of the transformer to add such pulse to the magnetizing current to exceed the current level of current passing through freewheeling rectifier to reduce that current to zero time when the freewheeling rectifier is turns off at zero current conditions. Further, the sum of the magnetizing current and the injected current provide the current required by the output inductor during the transition time. The amplitude of injected current is defined such that the sum is greater than the minimum current through the output inductor (at least by an amount that reflects into the primary winding). The amount of current reflected in the primary is chosen to be sufficiently large to discharge parasitic capacitances reflected across the primary main switch to zero during the transition time.

Abstract: An improved power distribution architecture includes a voltage regulator configured to operate with its output voltage approximately equal to its input voltage for most of the time. The regulator set point can be set to follow the input voltage within a limited range and set to a minimum or maximum set point outside the range. An improved ZVSBB controller adaptively extends the I-O phase of the converter while the input to output voltage ratio is close to one and responds to changes in input-output voltage differential within a short response time. The controller may respond asymmetrically to voltage changes with a steep response to voltage differentials in the boost range and a shallow response to voltage differentials in the buck range. An improved ZVSBB converter may achieve a peak converter efficiency greater than 99% owing to substantial reductions in switching and inductor losses within a narrow input range.
