Brief Description about Power Supply Designs and How They Operates?


The performance of each and every electronic system or electronic circuit depends upon the power supply design that energizes the circuit or system. It provides required current to the circuit. Any disturbance noise in this power supply design can cause problem in working or operation of circuit. If there is any deviation in the power supply design level, the circuit may not work properly. The accuracy and precision of circuit operation depends on it. In some of the circuits all the calibration are done at this voltage level. So, all these calibrations become false if there is fluctuation in supply level.

There are two types of power supplies named as unregulated power supply and regulated power supply. The unregulated power supply designed units are used in some circuits where there is no much change in require load current. The load current remains fixed or deviation is very less because in such supply the output voltage reduces as load current increases and the ripple in output voltage increases as load current increases.

So this kind of supply can’t be used where there is noticeable change in load current frequently. But although many circuits works on unregulated supply because it requires very few components and design is also very simple. Also some fluctuation in supply level can be tolerated due to load current change. The regulated power supply is required in digital circuits, the circuits in which the components can’t tolerate even 1% change in supply level like micro controller, micro processor etc.

Whether it’s an electronic noob or an expert engineer, all require this indispensable piece of equipment called the power supply unit. This is because no electronics can run without power, to be precise a low voltage DC power, and a power supply unit is a device which is specifically meant for fulfilling this purpose. The power supply design circuit will vary from simplest to the most complex depending on the necessity.

How to Pick the Best Laptop Desktop Power Adapter?

Image
Laptop Desktop power adapters are a frequently misunderstood and overlooked PC component. Many users choose a laptop desktop power adapter based on total wattage alone, assuming that higher is always synonymous with better. Others pay no attention to their selection at all and settle for whatever abomination arrived with their machine. But considering how important a good laptop desktop power adapter is to a system’s stability and long-term reliability, it’s a shame that they get so little attention in comparison to sexier components like graphics cards and SSDs.                                                     It doesn’t help that the power supply market is awash with products from unscrupulous manufacturers that use substandard components and overstate the hardware’s capabilities. Indeed, the abundance of power supply units’ related misinformati...

Travel Power Adopter- Smarter Technology for Smartest People

Image
Keeping gadgets charged up has become a necessity while travelling.  If you’re staying close to home, there are some adapters and chargers that prove very useful. Whether it’s a short trip across the pond or a worldwide adventure, having a travel power adapter along for the ride is an absolute must. It has a universal design that allows a multitude of plug-in options. It’s a wired world out there. If you plan to explore it with your must-have gadgets like cell phone, tablet, DSLR cam and more, you need to plug each of them into the local power grid. Because so many countries and even regions within countries developed their own electricity standards; thus, it’s safe to have a travel power adapter to prevent diversified power reigns. Technology Keeps You In-Touch with Tomorrow Technology plays an important role in our lives. We keep ourselves connected to others, we get to be constantly informed, and we make our lives easier by using smart devices.  Smart phone...

Standard Measures to Keep in Check While Selecting Best Medical Power Supply Units

Image
The term medical grade is applied to medical power supply units in a variety of package styles. These power supplies at a glance may look no different than their commercial grade counterparts. However, medical power supply units have been specially designed to meet and approved to the medical equipment safety standard which influences the internal power supply design. However, safety is not the only factor that distinguishes medical grade power supplies from commercial models. Medical equipment typically requires longer design cycles than other types of equipment and medical equipment designers often require more design support from the power supply vendor. Additionally, medical equipment usually has greater life expectancy than other equipment. Therefore, medical power supply units are designated as medical grade generally need to be supported by the power supply vendor for many years. Criteria to Follow for Selecting Best Grade Medical Power Supply Units Output Volt...
