Title: Cheng-Yang Li: Innovator in Power Control Circuits
Introduction
Cheng-Yang Li is a notable inventor based in Shenzhen, China. He has made significant contributions to the field of electronics, particularly in the development of power control circuits. With a total of 2 patents to his name, Li's work has had a considerable impact on computer hardware functionality.
Latest Patents
Li's latest patents include a "Time Sequence Control Circuit" and a "Power Control Circuit for Hard Disk Drive." The Time Sequence Control Circuit is designed to manage the timing sequence of a computer's motherboard. It ensures that a first voltage received by a power supply is greater than a preset voltage before a signal control terminal receives a second voltage during the computer's startup. Conversely, during shutdown, the first voltage drops below the preset level, effectively shutting off the second voltage supplied to the motherboard. The Power Control Circuit for Hard Disk Drive includes a first and second control circuit, along with connectors to manage voltage signals from the power supply to the hard disk drive. This innovation allows for compatibility with the timing sequence of the HDD, enhancing its operational efficiency.
