Latest Patents

One of Weixin Zhang's latest patents is the "Modular Multilevel Dynamic Switching DC-DC Transformer." This invention discloses a modular multilevel dynamic switching DC-DC transformer, which consists of N DC-DC sub-modules connected in series. Each of the DC-DC sub-modules features a symmetrical structure capable of realizing bidirectional power flow. The design includes two half-bridge sub-modules and isolating switches between capacitors of the two half-bridge sub-modules. This invention allows for dynamic switching in four different operating states of the DC-DC transformer, enabling voltage conversion and energy exchange. Compared to prior art, this invention significantly reduces the number of sub-modules, enhances economic efficiency, and minimizes the size of DC-DC transformers, making it advantageous for widespread adoption.

Another notable patent is the "Position-Sensorless Control Method and Apparatus for Brushless Motor." This method involves turning off a first driving voltage of a first phase coil and detecting the back electromotive force of the coil within a specified detection time. The invention determines a reference phase and cycle for a second driving voltage based on the detected back electromotive force. This approach effectively reduces costs, decreases implementation difficulty, and enhances system performance and reliability.
