Latest Patents

One of Kaplar's latest patents is the "High Voltage Gallium Nitride Vertical PN Diode." This innovative diode utilizes epitaxial growth of a thick drift region with a very low carrier concentration. It features a carefully designed multi-zone junction termination extension, which allows for high voltage blocking and high-power efficiency. An exemplary large area diode measuring 1 mm achieved a forward pulsed current of 3.5 A, with an 8.3 mΩ-cm specific on-resistance and a 5.3 kV reverse breakdown. Additionally, a smaller area diode of 0.063 mm was capable of 6.4 kV breakdown with a specific on-resistance of 10.2 mΩ-cm, demonstrating remarkable performance under specific conditions.

Another significant patent is the "Optically Switched Circuit Breaker with Cascaded Transistor Topology." This switching apparatus includes a transistor switch circuit connected between a power input terminal and a load terminal. It features a switchable bypass leg that is optically switched by a series-connected photoconductive semiconductor switch (PCSS). The design includes a cascade of three or more series-connected transistors and a resistor network to divide voltage across the transistors. The operation of this switch apparatus involves detecting fault conditions and redirecting electric current to ensure safety and reliability.
