Latest Patents
Among his latest patents, the Hybrid DC Circuit Breaker stands out. This invention includes a positive supply line connecting a positive input terminal to a positive output terminal, and a negative supply line linking a negative input terminal to a negative output terminal. It features a series connection of a first galvanic separation switch and a bypass switch in the positive supply line, along with a second galvanic separation switch in the negative supply line. A semiconductor switch element is connected in parallel to the bypass switch, and a series-connected inductor is present in the positive supply line. The operation of these components is controlled by a processing unit.
Another significant patent is the Selective Circuit Breaker. This device is designed to connect between a main supply line and a downstream circuit breaker. It includes a bypass switch in the supply line and a controlled semiconductor switch connected in parallel to the bypass switch. The selective circuit breaker is equipped with bypass switch off detection circuitry and short circuit detection circuitry, which control the bypass switch and the semiconductor switch according to a programmable switching characteristic. Notably, the short circuit current rating of this selective circuit breaker is designed to be substantially equal to that of the downstream circuit breaker.
