His innovative work focuses on matrix converters and overvoltage protection systems, which are essential for modern electrical applications.
Latest Patents
One of his latest patents is a matrix converter that features nine bidirectionally blocking power components arranged in a three-row matrix. These power components are strategically placed between three respective current conductors that run parallel to each other, both above and below the components. The current conductors above the matrix are oriented at a right angle to those below it. The interconnects to the gate and auxiliary emitter terminals are located on a thin insulating printed circuit board or film, which is secured to the corresponding contacts of the chips in recesses of the current conductors. Another significant patent is an overvoltage protection apparatus for a matrix converter. This apparatus includes nine bidirectional power switches arranged in a 3×3 switch matrix. It also features three varistors on both the network and load sides, connected in a delta configuration to the input and output connections of the matrix converter. This design results in a considerably reduced physical volume, leading to lower component costs for the overvoltage protection apparatus.
