The Prevalence Of Digital Power

 Technology of digital software has become pervading in area of switch power which was dominated by analog technology. In addition, digital-controlled supply is introduced into areas like LED lighting, power in cars and industrial devices. Effects are embodied with respect to aspects of power efficiency rise, products size decrease and development time reduction by adding communication functions and changing control mode.





Digital power will help to realize the miniaturization and high-efficiency for AC-DC supply and DC-DC converters. It has been drawing attention since five years ago and now it is enlarging with a quiet speed. Previously, it was only applied in un-interruptible supply, communication products, servers and solar power supplies. In recent years, digital power supply is applied in LED lighting devices, autos and even part of consuming products.


The main reason why digital power supply is used widely is that power-controlled IC products that use digital power supply are very cheap with price about 100 yen. As a result, companies are striving to develop this kind. Furthermore, digital power with DSP micro-controller is prevalent in areas with output power of more than 100W and switching frequency less than 1MHz.


Apart from that described above, it also has advantages in power property, development and application, for instance, the size of products will be decreased, numbers of components will be reduced and efficiency raised as well. However, there are some limitations together with its advantages. Not any power supplies can be applied with it and it is limited in power ability and switching frequency. Besides, cost limitation is also strict, and it will need some time for it to be entirely introduced. Related chip is: LC7980.

So you want to be a CISO: What you should know about data protection

Image
 Data is the lifeblood of any organization. Whether you’re a Chief Information Security Officer (CISO) or aspiring to become one, protecting sensitive business data will be your main priority. But the job isn’t getting any easier. In 2021, the number of data breaches climbed 68 percent to 1,862, costing an average of USD4.24 million each.1 The damage from a breach touches everyone, causing diminished brand equity and consumer trust, decreased shareholder confidence, failed audits, and increased scrutiny from regulatory agencies. It’s easy to become so preoccupied with protecting against the next ransomware attack that you overlook risks within your organization. Insider leaks of sensitive data, intellectual property (IP) theft, fraud, regulatory violations—any of these can crash a company (and your career) as quickly as a headline-grabbing breach. Given the breadth of today’s digital estate—on-premises, in the cloud, and at the edge—Microsoft Purview provides the inside-out, integr...

Evolution of Desktop Computers

Image
 The first debut of the modern computer today was during the World War II the ENIAC or the Electronic Numerical Integrator and calculator. It was made in order to hasten the computation of raw data and use it for military purposes. It was proposed to be used in the ballistic operations as well. The Americans have already prepared for the worst case scenario that the war won't end soon. The bright minds of their generations then conceived the idea of making a machine that can quickly modify data and use it for the war effort. The ENIAC however was done after the war. Nevertheless, it was a working contraption. It was the greatest discovery of humankind during that time. Complex equations and time consuming charts were done in a few minutes rather than hours. Moreover some problems and operations can be solved within a few seconds only. The problem with the ENIAC however was that of its size. It was too big and it consumes too much power. It was also too hassle to repair it fro...
