Abstract: A magnetic assembly is constructed comprising a first core portion, a second core portion, and a winding assembly. The first and second core portions each include a base portion and a plurality of projections extending from the base portion. The winding includes a plurality of stacked layers having conductive paths applied to their surfaces. The winding is constructed with a bore, wherein each conductive path encircles the bore. A number of the stacked conductive layers form a primary winding, and a number of the stacked conductive layers form a secondary winding. The winding is disposed over the first core portion in a manner so that a projection engages the opening of the winding to provide magnetic coupling of winding and core. The second core portion is disposed over the first core portion to form a closed magnetic circuit through and around the winding.

Abstract: Circuit apparatus for controlling a plurality of parallel connected batteries to equally share a common load is shown that includes an n parallel batteries connected to a common load element through a load current monitor that monitors the current through the load element, a battery current monitor for each battery, and a plurality of DC/DC converter circuits having outputs connected in series with each battery respectively. The load current output signal of the load current monitor is scaled down by 1/n, where n is the number of batteries, by a scale down amplifier circuit and distributed as a reference voltage to summing circuits where the scaled down load current is compared to the output of the battery current monitors. The outputs of the summing circuits are respectively connected as control signals to each of the DC/DC converters that are connected to each battery. Each DC/DC converter circuit adjusts it's output voltage to regulate the battery currents to I1 . . .

Abstract: There is provided a power system for a spacecraft that includes a plurality of electrical loads. The power system comprises N segmented solar array panels. Each of the N segmented solar array panels comprises Y solar array segments. The power system also comprises a plurality of power source blocks, each of which includes a respective one of the Y solar array segments of a respective one of the N segmented solar array panels. The Y solar array segments receive solar energy and provide electrical energy as outputs of respective ones of the power source blocks. The power system further comprises at least one switch which is controllable for coupling electrical energy output by individual ones of the power source blocks to selected individual ones of the electrical loads.
