Title: The Innovative Contributions of Sang Ton Ngo
Introduction
Sang Ton Ngo is a notable inventor based in Cupertino, California, recognized for his significant contributions to the field of power conversion technology. With a total of six patents to his name, Ngo has developed innovative solutions that enhance the efficiency and reliability of power systems.
Latest Patents
One of his latest patents is titled "Optimal control of wide conversion ratio switching converters." This invention utilizes a switch state controller that generates a pulse train, which is employed in a power converter with multiple stages. The unique aspect of this design is that all stages are simultaneously controlled by a single switch, enhancing the converter's performance. The on-time of the pulse train is adjusted based on input characteristics, while the period is determined by the output characteristics. This innovation facilitates the development of AC-to-DC converters, including power-factor-correction converters, and DC-to-DC converters with high conversion ratios, minimal parts count, and increased reliability.
Another significant patent is the "Apparatus and method for adaptively controlling power supplied to a hot-pluggable subsystem." This invention addresses the inrush current control of hot-pluggable subsystems when connected to power sources. The method involves adaptively controlling a pass device by monitoring the gate voltage during the initial charging phase. This approach allows for the detection of short-circuit conditions and includes features such as automatic restart circuitry and under-voltage lockout circuitry, providing a robust solution for power management.
