Confessions of a Digital Power Researcher

1. The only way to power supply ---digital power supply

Linear power supply, switching power supply , digital power supply, although the power supply is not as fast as the CPU generation, but it is also constantly improving. I feel the most deeply when providing digital power system solutions for customers. Foreign companies already have a variety of digital power products ranging from 100W to 2KW. The provision of solutions not only includes hardware, software, sample reference design or a patent or a chip . Technological innovation is considered from the perspective of the entire system. From a deeper financial perspective, since product development requires a certain amount of upfront investment, after each new product is launched, the manufacturer will go through a process from debt to break-even point and then to profit. The profit margin of new products is very tempting, but the investment and risk make them hesitate. If the new product can share part of the upfront cost of the old product and see the opportunity clearly, the manufacturer will be moved to take action and invest in innovation.

Why should power supply companies develop digital power supply at this time? How can domestic companies remain indifferent?

The emergence of revolutionary technology is an opportunity for the company that possesses it to surpass others and stand out from the crowd. It has a huge impact on improving the company's intangible assets and future markets. For example:

1. Vaccine: Blood-derived vaccine - Gene vaccine

2. Aircraft: Propeller plane - Jet plane

3. Television: Analog TV – Digital TV

4. Camera: Film Camera – Digital Camera

5. Power supply: switching power supply (analog technology) - digital power supply

2. Look at digital power supply with "viewpoint" thinking-the periphery is the center

In his book "The Big Trend", Naisbitt successfully predicted the rise of the Internet and global integration, and his predictions have almost all become reality in today's American society. In his new book "Opinions", Naisbitt simplifies the complex and summarizes eleven "Opinions" to teach people how to think and how to see the future. He has extraordinary foresight and foresight, but foresight is ultimately a kind of imagination with a relatively fixed thinking mode. Time has proved his foresight. Accurately predicting future trends and seizing opportunities in time often achieves twice the result with half the effort.

1. Although many things change, most of them follow certain rules.

Technology is constantly improving, ISA, PCI, PCI-Experss, linear power supply, switching power supply, digital power supply

2. The future is hidden in reality

Everyone should be able to see the trend, managers (strategy), engineers (new technology), students (career in 4 years)

3. Pay attention to the results of the game

The result is your own choice and it is difficult to change

4. Don’t be afraid to make mistakes

Who will make mistakes, those who plunge into digital power or those who stick to their own city?

5. Treat predicting the future like a jigsaw puzzle

Digital power template: concepts, IC, design, SMbus, market, programming...

6. Don’t be so far ahead in the pack that people forget you’re one of them.

Now, no one in the power supply industry pays attention to you, just like the literary world did not recognize Wang Xiaobo.

7. People will not resist change when there is real benefit

After the pioneers of digital power supply have paved the way, followers will come like vultures

8. Things we expect always happen slower than we expect

Changing people's minds is the most difficult thing; making products is much easier.

9. Success does not come from solving problems, but from taking advantage of opportunities

Was the turning point of "computer digital power supply" at a certain exhibition or after it was made public in the United States?

10. The old goes, the new comes

The conventional way of thinking makes it impossible for people to judge new things, but this does not prevent old things from being replaced.

11. Don’t forget the two sides of technology

3. One of my US computer patents

After four years of review procedures, the "Method and Device for Monitoring Computer Power and Chassis" was finally approved by the US Patent Office. This is an invention related to computer power supply, involving the basic parameters u, i, T, n ( voltage , current , temperature, fan speed, etc.) that need to be monitored by the power supply, and is technically fully compatible with the ATX specification. Unlike MP3, DVD, and Bluetooth, which have few intellectual property rights and only charge processing fees, and are also different from the price competition in the PC industry; digital power supply is a rare field in China with core intellectual property rights! The power supply industry is very large in China, and already has many resources such as market, channels, factories and personnel, and only needs a little spark of thought.

Summary of the manual

The present invention discloses a method and device for monitoring a computer case and a power supply. On the system management bus of a computer, which is a master device, a monitoring chip is extended as a slave device on the system management bus to form a monitoring device, and the fan speed, temperature and working voltage in the case and the power supply are measured. After the temperature signal obtained by the temperature sensor is input into the monitoring chip, it is processed by the monitoring chip and a control signal is output. The fan speed is controlled by the amplifying driving circuit . The system management bus in the present invention is connected to the system management bus connector on the PCI Express board, PCI board or motherboard. By using the method and device of the present invention, an intelligent case and power supply can be constructed to make the whole machine silent and energy-saving. The system management bus communicates with the computer host through the system management bus, and the running status is monitored by the program, which is helpful to more reasonably manage the computer case and power supply equipment.

4. Things I want to do after completing the digital power supply

After the patent of computer digital power supply is completed, production should be the responsibility of manufacturers. My thoughts can't stop like a satellite revolving around the sun, thinking about several new problems generated in the previous process, and the application prospects are very broad.

1. Development of a new bus (non-PMBus): This bus controller has been integrated on the CPU chip. Given the global dominance of the Intel empire, this is a new technology that is worthy of attention.

2. Design, production and application of a humidity SOC: Every computer has temperature monitoring, but why are there few humidity measurements? It is because there is no easy-to-use humidity SOC, which is the size of a fingernail, contains a humidity sensor and a standard interface, has 80% of the design completed, and can be produced by IC companies or commissioned by computer companies.

3. Monitoring programs and their associated applications with instant messaging software and mobile phones: Suitable for content service companies and software vendors in the communications field, such as mobile content providers or small companies that write Foxmail programs. Then you can apply for software registration to protect it.
