Title: Innovations of Inventor Hung-Ta Hsu
Introduction
Hung-Ta Hsu is a notable inventor based in Zhudong, Taiwan. He has made significant contributions to the field of power conversion technology, holding a total of four patents. His work focuses on improving the efficiency and functionality of power converters.
Latest Patents
One of his latest patents is a flyback converter designed for controlling on-time variation in AC/DC conversion technology. This flyback converter features a primary side and a secondary side. The primary side includes a main switch that connects a primary coil to the input of the flyback converter in series. The secondary side includes a secondary coil that couples with the output terminal of the flyback converter. When the switching frequency of the main switch is set at a preset first on time, the on-time of the main switch continuously adjusts according to output load changes. When the switching frequency exceeds the first switching frequency, the on time remains constant. This linear control of on time helps to minimize excessive changes in output voltage ripples, thereby enhancing circuit efficiency.
Another significant patent involves a signal transmission circuit that provides control information from the secondary side to the primary side of a power converter. This circuit includes a transmitter circuit, a signal transformer, and a detection circuit. The transmitter circuit generates a ramp signal based on a first control signal from the secondary side, which indicates the control information for a switch on the primary side. The signal transformer converts the ramp signal into an output signal that includes both positive-going and negative-going components to convey the control information. The detection circuit then detects these components to provide the necessary control information for the switch.
