Title: Innovations of Chun-Hsing Wu in Cathode Ray Tube Technology
Introduction
Chun-Hsing Wu is a notable inventor based in Singapore, recognized for his contributions to the field of cathode ray tube technology. With a total of 3 patents to his name, he has made significant advancements that enhance the functionality and efficiency of electronic devices.
Latest Patents
One of his latest patents is focused on an auto degaussing system that transitions from standby to on mode. This invention involves a circuitry designed to control the power supply of a degaussing coil in a cathode ray tube. The circuitry is equipped with inputs connected to a direct current source from a switched mode power supply, which operates at different frequency ranges depending on the power state. The detecting circuit within this system identifies changes in switching frequencies, allowing for precise control of the degaussing coil's operation.
Another significant patent by Chun-Hsing Wu is the stray emission reduction circuit. This innovation addresses the common issue of stray emissions in cathode ray tubes, which are typically mitigated by installing an expensive bleeder resistor. Instead, his circuit differentiates the H pulse when the TV set switches from 'on' to 'standby', resulting in a higher duty cycle for the control transistor. This effectively lowers the flyback peak voltage at the anode, thereby reducing the EHT voltage and improving overall performance.
