A homopolar multi-core energy conversion device is an apparatus that uses magnetic flux commutation instead of a combination of electrical current commutation and brushes. The apparatus includes a first discontinuous annular stator core, a second discontinuous annular stator core, and a rotor core. The first discontinuous annular stator core is configured to generate a circumferentially-segmented clockwise magnetic flux around the rotor core, while second discontinuous annular stator core is configured to generate a circumferentially-segmented counter-clockwise magnetic flux around the rotor core. The rotor core is configured to radially partition a traversing magnetic flux. The circumferentially-segmented clockwise magnetic flux, the circumferentially-segmented counter-clockwise magnetic flux, and the traversing magnetic flux interact with each other so that the apparatus can function either as a motor or as a generator. The aforementioned components of the apparatus can be configured into different embodiment to achieve the same function.

Systems and methods are disclosed for intelligent circuit control for solar panel systems. In one embodiment, an example method may include determining, by a controller, that a first electrical output of a first solar panel configured to charge a plurality of rechargeable batteries is greater than a second electrical output of a second solar panel configured to charge the plurality of rechargeable batteries, and causing the second solar panel to be disconnected from the plurality of rechargeable batteries. Example methods may include determining that a voltage potential of the plurality of rechargeable batteries is greater than a total output voltage, where the total output voltage is a sum of the first electrical output and the second electrical output, and causing a connection between the plurality of rechargeable batteries to be changed from a series connection to a parallel connection based at least in part on the first electrical output.

Pairs of unidirectionally magnetic rotor/stator assemblies are mounted for synchronous rotation and complementary, so that one creates pulsating positive current flow and the other creates pulsating negative current flow, as the rotor and stator in each assembly are rotated with respect to each other. The pulsating positive current flow and pulsating negative current flow are combined at a desired phase angle to create alternating current, without power loss due to reversal of current flow.

The rotary electrical machine having a homopolar structure includes a number Npe of electrical phases. The machine includes a juxtaposition, along the rotational axis of the rotary electrical machine, of at least one pair of armatures having a number of poles Np, placed on both sides of at least one inductive coil wound around the rotational axis, two adjacent armatures being angularly offset by any electrical angle θs, preferably between 0° and 180°/Npe, and at least one “passive” inductor of ferromagnetic material, separated from the armatures by an air gap. Either the armatures form the rotor, or the inductor and the other element form the stator.

A homopolar alternating current machine (HAM) is disclosed which includes a stator having a plurality of segments radially protruding outward, each segment includes a main winding, a first auxiliary winding, and a second auxiliary winding, whereby each of the first and second auxiliary windings are coupled to each other in a parallel manner, a first rotor disposed proximate the stator, a second rotor disposed proximate the stator, and a dc flux source corresponding to each of the first and second rotors, whereby substantially no excitation of the first and the second auxiliary windings of each stator segment of the plurality of segments is needed to operate the HAM, whereby when energized, there is substantially no DC flux in each of the main winding, wherein operating the HAM results in a substantially sinusoidal current waveform without a DC offset, and wherein the HAM can be operated as a motor or generator.
