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.

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 phones, tablet

Understanding Energy Efficiency for Medical Power Supply Units

Image
Energy efficiency legislation is now in place across most regions of the world. In the main, the focus of these regulations is on the operating efficiency and the no-load standby power consumption of medical power supply units. Driven by the proliferation of external medical power supply products and the environmental impact of leaving power supplies always turned on despite the load not being in use, most legislation set limits for what is considered to be a viable no-load consumption. Being better able to control and lower the power consumed by external medical power supply units, whether a load is connected or not, helps to deliver a significant reduction in the environmental impact. In the USA, there are a number of bodies legislating on energy efficiency; the California Energy Commission, US Congress with its Energy Independence and Security Act and recently the United States Department of Energy. There is also Energy Star that sets limits for electrical and electronic

Challenges Engineers Face during DC-DC Power Supply Design

Image
Electronic system designers, program managers, engineers, and original equipment manufacturers must address numerous challenges in the selection or development of an appropriate power supply for their systems. These challenges include a multitude of aspects related to the product development cycle, time-to-market, reliability and warranty, parts availability, and life cycle costs. In some cases, an existing power supply can be readily adapted from a different application. In other cases, it may be necessary to develop a new or custom power supply. Let’s examine the major challenges faced in the design of DC-DC power supplies and determine the solution. Top Challenges Faced by Engineers during DC-DC Power Supply 1.     Physical Size : Much as Moore’s law observes an increase in the number of components in a decreasing amount of available space, so too have advances in miniaturization technologies had a dramatic impact on the DC-DC power supply industry. Electronic systems
