The TV, camera, etc. in the communication, network and home appliances in the IT system have been digitized, and the last fortress to be broken is the power supply. Power analysts at market research institutes say that the power industry's turn to switch-mode power supply was a big change 30 years ago, and now the power digitalization trend is likely to be a bigger change. Power experts have said that digital power will be a revolution in power technology. Digital power provides intelligent adaptability and flexibility with the ability to directly monitor and adapt to system conditions to meet any complex power requirements. A few years ago, domestic and foreign companies began patent distribution and seized the commanding heights of digital power.
We know that digital power is "a communicable power product with monitoring capabilities and control of the entire power loop."
We divide this into three parts with the underlined line. My invention covers the monitoring and communication parts. What is monitored? Input voltage / current, output voltage / current, temperature, fan speed, all power is such a few, and the communication part is SMBus (or I2C and PMBus), this is the standard bus of digital power, the intel chipset fully supports . For DSPs and MCUs that control the entire power supply loop, there are several technical solutions for major digital power chip providers, which are not covered by our invention. Our invention can be well integrated with switching power supplies and with DSP and MCU digital controllers.
The solution we advocate is: switching power supply + digital monitoring, that is, analog / digital hybrid digital power supply, such digital power technology is mature and simple. 90% of the devices are switching power supply devices, 10% of the devices are digital monitoring devices, and digital monitoring devices with SMBus communication interfaces can be completed using a single chip. Existing switching power supply production technologies and pipelines can continue to be used, allowing a smooth transition to an all-digital power supply.
Digital power scheme 1: switching power supply + digital monitoring input voltage / current, temperature, fan speed, can refer to patent: China 2005100192642
Digital power scheme 2: switching power supply + digital monitoring output voltage / current, temperature, fan speed, can refer to patent: US Patent No 7463999
Of course, digital power solutions 1, 2 can also be combined, which is a project that has not been done before in the field of computer power.
Digital Power Solution 3: DSP Digital Control + Digital Monitoring, TI and other large companies offer several options. There are UPS applications in the application, many articles on digital power have their descriptions, big companies are rich in advertising and promotion.
Someone asks 1: This analog/digital hybrid digital power supply needs to be paired with a computer host. How to use it on a host without SMBUS or I2C interface?
A1: You are right, SMBUS or I2C is required for host (or motherboard) support. All computer hosts or motherboards support SMBUS. It is easy to ignore that PCI and PCI-express buses also support SMBUS. It can be used by adding a PCI and PCI-express board as an interface. We also have a patent on this point, the patent name SMBUS expansion device, patent number, patent Can be seen on the bureau or on my blog link. An interface card is very simple, and it is difficult to counterfeit as a patent.
Someone asks 2, the basic working principle of your patent is actually that some monitoring functions are available in many industrial control products (computer mainframes). Do you have any special places?
A2, the patent rights of each country are authorized to the earliest inventors. Now the monitoring function is applied on industrial control products and computer mainframes, but I was the first to introduce it to the power supply. In 2004, I submitted the relevant computer power supply and SMBUS. The patent, the international power management bus PMBUS is only available in 2005! There is no doubt that this time we are ahead of international industry standards! Is there such an example there? ! The examinations of inventions by national patent offices are extremely strict. Now China and the US Patent Office have approved our inventions. The largest power producers and countries with the most advanced technology have been approved and protected by law. The patent mutual recognition system implemented by the three parties in the United States, Japan and Europe, which was newly implemented in 2008, opened the door for patent protection in the global market. In addition, no one has ever questioned the serial bus. Why is SMBUS patentable after I2C? Because the inventor is intel, and some of our inventions will be suspicious.
Digital power is not the most advanced technology for genetic engineering or landing on Mars. The same thing is that innovation and courage are also needed here, which is also full of opportunities and challenges. Based on the annual volume of 260 million PCs per year, there is a vast market with unparalleled advantages. China's Guangdong region has concentrated most of the world's power plants, but they have no essential difference from toy factories. There are few core technologies and lack of innovation. Our invention makes their power upgrade possible. Being exempted from electronics manufacturers to repeat the chaos of MP3 and switching power supply low-cost competition, the regular power supply market is definitely better than the disorderly power supply market.
After painstaking work, we have completed the digital power patent pool, project feasibility study report, development program, and can provide you with a full range of services. Related patents and reports can be found on my blog and links, "Computer Digital Power" Google is the first one. Our invention is based on two major foundations: 1 is the system management bus of intel, and 2 is the monitoring IC chip. In addition to PCs and servers, industrial instruments, medical equipment, communication equipment, etc. all use Intel's CPU, which naturally becomes our digital power user. The monitoring IC chip with system management bus has many finished products. In addition, I2C in IBM's POWER series computers can also use the digital power patent we invented.
As one article says, “Improve profit margins for low-tech innovations!†Digital power turns computer peripherals into subsystems that can be monitored, doubling the value of power. Next, see who is faster to adapt to the trend of change, in the blue sea of ​​digital power to test who is fast fish who is slow fish.
