Title: Innovations by Ying Chieh Su
Introduction
Ying Chieh Su is a notable inventor based in Sijhih, Taiwan. He has made significant contributions to the field of power factor control through his innovative designs. His work is characterized by a focus on enhancing the efficiency of electrical systems.
Latest Patents
Ying Chieh Su holds a patent for a "Switching control circuit for discontinuous mode PFC converters." This invention features a switching control circuit that includes a detection terminal, input terminal, ramp generator, program terminal, error amplifier, mix circuit, and delay circuit for power factor control. The detection terminal generates a detection signal in response to the inductor discharge. The input terminal is connected for detecting a switching current signal. The program terminal determines the slew rate of the ramp signal and the maximum on-time of the switching signal. An error amplifier generates an error signal for regulating the output. A mix circuit generates a mixing signal proportional to the ramp signal and the switching current signal. The switching signal is turned on in response to the detection signal and is turned off based on the error signal. The slew rate of the mixing signal is increased in response to the increase of the input voltage, while the on-time of the switching signal is increased inversely proportional to the input voltage.
