Latest Patents

Pacifique Maisha holds a patent for an "Alternator with Harmonic Compensation." This system is designed to detect and eliminate harmonic effects in the DQ plane of non-sinusoidal back electromotive force (BEMF) voltages. The technology utilizes a field-oriented controller (FOC) that incorporates a poly-phase electric machine, proportional-integral-derivative controllers, and a microcontroller. The microcontroller plays a crucial role by analyzing both stator current and BEMF voltages to extract flux vectors of the EMF. These vectors often exhibit distortions due to the geometries and saturation effects inherent in electrical machines. To correct these defects, the microcontroller transmits the BEMF vectors and machine operating points, including current rotational speed and current, into an algorithm. This algorithm generates a command voltage in the DQ frame for specific operating points, which is then used to prevent non-sinusoidal back EMF voltages from generating non-sinusoidal currents.
