Title: Chihwei Chang: Power Conversion and Limited Power Supply Protection
Introduction
Chihwei Chang is an inventor based in Hsinchu, Taiwan. His patent work includes a power conversion apparatus designed to protect limited power supplies.
Latest Patents
Chang is associated with 1 patent: “Power Conversion Apparatus for Limited Power Supply Protection.” The invention uses a bargaining circuit to adjust the feedback voltage from an optocoupler, prompting a control circuit to reduce the transformer circuit’s output voltage. When that output falls below a specified setting voltage, the apparatus turns off the optocoupler to increase the feedback voltage. The control circuit then performs a limited-power operation when the output voltage is below the first setting voltage and the feedback voltage exceeds a second setting voltage.
Career Highlights
Chang is associated with Power Forest Technology Corporation. His patent describes a control approach for managing output voltage and limited-power operation in a power conversion apparatus.
Collaborations
Chang’s listed coworkers include Rong-Jie Tu and Chien Lung Li.
Conclusion
Chihwei Chang’s patent focuses on protecting limited power supplies through coordinated feedback and voltage control in power conversion equipment.
