Title: Fong Cheng Yang: Innovator in Power Control Technologies

Introduction

Fong Cheng Yang is a notable inventor based in Zhubei, Taiwan. He has made significant contributions to the field of power control technologies, holding 2 patents that showcase his innovative approach to solving complex electrical challenges.

Latest Patents

His latest patents include a "Power controller and control methods for reducing output voltage ripple when line voltage is low." This invention involves a control method utilized in a switching-mode power supply that delivers an output voltage to a load. The system detects a line voltage generated by rectifying an alternating-current voltage and compares it with a first reference voltage. A control signal is generated based on this comparison. When the line voltage falls below the first reference voltage, the control signal is employed to increase the converted power supplied by the switching-mode power supply to the output voltage. Conversely, when the line voltage meets or exceeds the first reference voltage, the control signal does not affect the converted power.

Another significant patent is the "Power controller and relevant control method capable of providing open-circuit protection." This power controller offers open-circuit protection for a power supply when an open circuit occurs between the ground end of an auxiliary winding and the input ground. It generates a PWM signal to determine the ON and OFF times of a power switch connected in series between an input voltage and the input ground. A deviation detector within the power controller monitors the winding voltage at a floating end of the auxiliary winding during the ON time. It asserts an open protection signal when the winding voltage variation meets a predetermined condition, ensuring the power switch remains OFF and providing open-circuit protection.
