Latest Patent Applications

Shuyu Ou's notable patent application is titled "APPARATUS AND METHOD FOR LIMITING INRUSH CURRENT AND EXTENDING HOLD-UP TIME IN AN AC-DC POWER CONVERTION APPARATUS." This application describes an AC-DC power converter that includes a power factor correction stage, which receives grid power and produces DC bus power. The design features a DC-DC converter stage that takes the DC bus power and generates a DC output power. The energy storage system is composed of a larger capacitance value first capacitor and a smaller capacitance value second capacitor, which are coupled in series across the DC bus power. A switching device is connected in parallel with the smaller second capacitor. During the start-up of the converter, the switching device is turned off to control inrush current by transferring energy from the second capacitor to the first capacitor. When the converter is operational, the switching device is activated, allowing the first capacitor to provide energy storage for the DC bus power. In the event of grid power disconnection, the hold-up time is extended by turning off the switching device and transferring energy from the first capacitor to the second capacitor.

Conclusion

Shuyu Ou's work in AC-DC power conversion technology showcases her innovative spirit and dedication to improving energy efficiency. Her contributions are poised to make a significant impact in the field.
