Latest Patents
One of his latest patents is the "Stacked switched capacitor energy buffer circuit." This invention includes a switching network and multiple energy storage capacitors. The design operates at a relatively low switching frequency, allowing for soft charging of the capacitors, which reduces energy loss. This results in a high efficiency compared to other energy buffer circuits. Notably, the architecture does not require electrolytic capacitors, overcoming limitations associated with traditional energy buffers. The SSC energy buffer architecture achieves an effective energy density characteristic comparable to those using electrolytic capacitors, with losses that scale with the amount of energy buffered.
Another significant patent is the "Method and apparatus for producing an asymmetric magnetic field." This system generates an asymmetric magnetic field through a drive circuit and a stacked winding structure. The structure consists of multiple winding layers, including a first winding layer with a first conductive winding and a second winding layer with a second conductive winding. This arrangement produces a stronger magnetic field on one side of the structure compared to the other when electrically driven.
