Latest Patents
One of his latest patents is the "Surface Mounted Heat Buffer." This invention involves an assembly designed to dissipate heat generated by a heat-generating electrical component that is surface mounted on a circuit board. The assembly includes a heat buffer made of a thermally and electrically conducting material, which is soldered to a thermal flag of the electrical component. Additionally, it features a heat sink in thermal contact with the heat buffer, along with a galvanic separation between the two. This design allows the heat capacitance of the heat buffer to absorb short-term increases in heat dissipation, significantly improving the performance of the surface-mounted component.
Another notable patent is the "DC Bus Ripple Reduction." This invention outlines an electrical motor system and a method for its operation. The system comprises a direct current (DC) source, a filter connected in parallel with the DC source, and an electric motor with at least two sets of windings. The voltage signal from the DC source is modulated by an inverter circuit and supplied to each set of windings with a respective time offset. This innovative approach enables efficient DC bus ripple reduction, allowing for the use of smaller filter capacitors in electrical motor systems.
