Latest Patents
One of Jianhong Xu's latest patents is titled "Circuits for Softening Switching Phases in Voltage Converters." This invention relates to a circuit designed to provide current from a source to a load. The circuit features a commutation cell that includes a main switch controlling the voltage applied by the source to the load. An opposite switch is incorporated to maintain the current in the load when it is disconnected from the source by the main switch. This innovative design reduces recovery current, losses, and electromagnetic losses. Additionally, a synchronizing controller manages the opening and closing sequences of both switches, enabling the circuit to function as a DC-DC voltage converter. When two such circuits are combined, they can create a DC-AC voltage converter.
Another significant patent by Xu is the "Multi-Position Clutch." This invention allows for the selective coupling of at least two of three rotatable shafts. The clutch comprises cooperation elements associated with each shaft for selective engagement. An actuating mechanism is included to facilitate the coupling of adjacent cooperation elements, enhancing the functionality of mechanical systems.
