Latest Patents
Two of Liang Shao's most recent patents exemplify his innovative work. The first is a **Power Inverter Controller and Method**, which features a controller designed for a power inverter with a gate assembly that outputs alternating current power. This invention includes a gate driver that manages the gate assembly's activation and a processor tasked with controlling the operations of the gate driver. A current sensor offers an output signal indicative of the current flowing at the power output. Additionally, a noise detector circuit relays the frequency of electromagnetic noise to the processor, allowing it to sample current at that specific frequency.
The second patent is for a **Method and Apparatus for Reducing EMI Emissions from a Power Inverter**. This invention is particularly suited for hybrid automotive vehicles. It consists of a case that contains at least one electrical port for connecting internal electrical signals to an external device. Importantly, a non-electrical sensing conductor runs through each electrical port and its associated cable connector, which detects any breaks in continuity, thereby generating a signal to indicate such breaks. This design significantly minimizes EMI emissions and enhances the overall reliability of the inverter.
