Title: Innovations of Yu-Ming Tsai in Voltage Conversion Technology
Introduction
Yu-Ming Tsai is a notable inventor based in Tainan County, Taiwan. He has made significant contributions to the field of voltage conversion technology, holding two patents that showcase his innovative approach to electrical engineering.
Latest Patents
One of Yu-Ming Tsai's latest patents is a Buck-Boost Voltage Converter. This invention features an input switching unit that selectively couples a first terminal of an inductor with an input voltage and a ground potential. An output switching unit is designed to selectively couple a second terminal of the inductor with an output voltage and the ground potential. The invention includes a first pulse generating circuit that produces a first pulse signal with a first duty ratio, modulated in response to the output voltage. Additionally, a second pulse generating circuit creates a second pulse signal with a constant duty ratio that is larger than zero and smaller than one. When the first duty ratio exceeds a predetermined threshold, a mode control circuit applies the first pulse signal to control one of the switching units and the second pulse signal to control the other.
Another significant patent by Yu-Ming Tsai is a Light Loading Control Circuit for a Buck-Boost Voltage Converter. This circuit operates the switching circuit of a buck-boost voltage converter alternately in multiple phase cycles and a sleep period. Each phase cycle consists of a rising phase, a falling phase, and a maintaining phase. During the rising phase, the switching circuit increases the inductor current, while in the falling phase, it decreases the inductor current. The maintaining phase keeps the inductor current approximately constant. The sleep period ensures that the two terminals of the inductor are not coupled to the input voltage, output voltage, or ground potential.
