Latest Patents

One of Ronghui Li's latest patents is titled "Method and apparatus for increasing a current sensing range in a polyphase motor system." This invention involves a method for enhancing the current sensing range in vehicles or other polyphase motor systems. The process includes measuring phase currents delivered to a motor, calculating the absolute value of each phase current, and determining whether any sensor is saturated. The controller then extrapolates the phase current value of the saturated sensor to ensure accurate control actions are executed.

Another notable patent is "Methods, systems and apparatus for reducing power loss in an electric motor drive system." This invention provides methods and systems aimed at minimizing power loss in electric motor drive systems. The controller assesses whether a torque command is below a minimum threshold and, if so, increments a counter to monitor the situation. If the torque command remains low, the controller can generate a disable signal to optimize the inverter module's performance.
