Latest Patents

James H Gu holds a patent for a "Control system for switching loads on zero crossing." This AC load switching system predicts when a zero voltage cross-over condition will exist for the purpose of switching an AC load. The system is designed to minimize inrush currents by characterizing the switching devices, which are typically electromechanical. The processor within the system stores characterization parameters for the load switching elements, including closure delay time and bounce time intervals. By energizing a switching element at the right moment during the AC line cycle, the system ensures that the line voltage is at a zero voltage condition when the contacts close, thereby reducing inrush current.
