Latest Patents
Huan Yang’s latest inventions exemplify his expertise in enhancing power management systems. His first patent details a **method for DC islanding detection based on positive feedback of bus voltage at a specific frequency**. This method is structured around a three-step procedure: extracting a specific frequency component from the bus voltage, injecting a disturbance at that frequency, and subsequently determining whether DC islanding has occurred. It leverages a positive feedback mechanism to create self-excited oscillations in islanding mode, effectively allowing for stable operations in the grid-connected mode.
The second of Yang's patents introduces a **high step-down modular DC power supply**. This innovative power supply features an upper and lower modular cascade circuit string, both equipped with sub-module circuits that allow for flexible configurations. This design enables the power supply to achieve a significant voltage step-down ratio, dispensing with the need for synchronous control signals among sub-modules. The result is a simple control strategy that enhances efficiency and adaptability in medium to high voltage applications.
