Latest Patents
Karen holds a patent for a solid-state protection circuit designed for electrical apparatus. This invention safeguards electrical equipment from damage caused by faults through a circuit that provides multiple levels of protection. The design incorporates a semiconductor switch and a current sensor in series with the electrical equipment. When the current exceeds a first threshold for a specified duration, the semiconductor switch becomes non-conductive until the circuit is reset. If the current surpasses a greater second threshold, a pulsed signal alternates the semiconductor switch between conductive and non-conductive states, ensuring the average current remains within acceptable limits. In cases where the current exceeds an even greater third threshold, the semiconductor switch is immediately rendered non-conductive until a manual reset occurs.
