With a total of 2 patents, his work focuses on enhancing the efficiency and safety of electrical switching mechanisms.

Latest Patents

Frank Heerdt's latest patents include the "Arc extinguishing switch and switching method thereof." This invention discloses an arc extinguishing switch that comprises a mechanical switch and a first electric branch connected in parallel with the first contact branch of the mechanical switch. The first electric branch includes a first controllable unidirectional turn-on subbranch and a second controllable unidirectional turn-on subbranch, which are controlled by two thyristors. This design lowers the high power requirement for the thyristor and reduces product costs while preventing the mechanical switch from being bypassed during short-circuit failures.

Another significant patent is the "Arc extinguishing hybrid transfer switch and switching method." This invention features a mechanical switch and a first thyristor branch connected in parallel with the first contact branch of the mechanical switch. The design allows for the use of low-power thyristors, greatly reducing the cost of the switch. Additionally, it enables the polarized capacitor to replace the thyristor for arc extinguishing during short-circuit failures, thereby minimizing the load current and the impact of thyristor failure on the load.
