Title: Innovations by Shu-Yuan Chin
Introduction
Shu-Yuan Chin is a notable inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of fan control technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Fan Linear Speed Controller." This invention controls the rotation speed of a fan using an external fan control voltage. The controller includes a temperature sensor unit, a linear speed control unit, and a fault detection unit. The temperature sensor unit utilizes a thermistor to detect the ambient temperature, generating a thermally sensitive voltage. The linear speed control unit processes both the external fan control voltage and the thermally sensitive voltage to produce an output voltage that drives the fan. This output voltage is proportional to the fan control voltage under specific conditions. The fault detection unit monitors the thermally sensitive voltage and the rotation speed signal to identify any abnormalities in the fan's operation.
Another significant patent is the "Brushless DC Fan Driver with Overshoot Voltage Prevention and Enhanced Performance." This fan driver is designed to operate a DC brushless fan. It features a pulse generator that receives a signal from a Hall element, indicating the rotor's phase. The generator produces two pulse signals that are phase-inverted by approximately 180 degrees. Two driving units, activated by these pulse signals, apply current to the fan's coils, generating magnetic fields that rotate the rotor. Additionally, switch elements are included to transfer anti-electromotive voltage between the coils, enhancing the driver's efficiency.
