How to choose UPS power supply for the computer room? (Part-2)

Jun , 27 2022

Enterprise data centers are becoming more and more important nowadays. How to ensure the stable operation of enterprise data centers has become a very critical factor. UPS is a standard accessory for many enterprises in data centers, so how to choose a UPS power supply suitable for enterprise applications? In our last article we discussed about some options, now we are going to discuss in details....

Efficiency of DC power system

Jun , 27 2022

In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

Theoretical introduction to an AC power system

Jul , 22 2022

AC Power Systems have plenty more units, terms, measurements, interesting waveforms and math to describe their behavior. Any formulas presented here are for reference and validation only. The intension of this paperis convey the concept without having to seriously crunch numbers. All the terms and formulas interweave so itis difficult to create a flow of one topic to another without skipping aroun...

What are the soft costs of datacenter?

Jul , 22 2022

Data centers can’t afford to go dark. That’s why reliable critical power systems arecentral to their operation. Selecting and maintaining these systems comes at a price, but astronger understanding of “hard” and “soft” costs -- and what can be done to mitigate thelatter -- can protect the bottom line. Hard and soft costs vary from one operation to the next. In general, hard costs refer to the expe...

How to lower the soft cost of Data center

Aug , 01 2022

Outages are a major fear for data centers. And for a good reason. Unfortunately, many companies still roll the dice by purchasing critical power systems,assigning someone internally to keep tabs on the equipment, and simply hoping the system comes through when it needs to. (Spoiler: it often doesn’t.) Scarce resources, a lack of skilled personnel, and increased edge computing (and the scattered fa...

Solar battery life time

Aug , 08 2022

There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

Power Factor and Harmonic Analysis in Single phase AC to DC converter

Aug , 15 2022

Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part ofmost of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC toDC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is used ...

Classification of inverters based on wave type (Pure Sine wave)

Aug , 29 2022

Power inverters can be mainly divided into pure sine wave inverters and modified sine wave inverters according to their waveforms. In fact, there is another type - square wave inverter, the earliest inverter, which is rarely seen now. Pure sine wave inverter The pure sine wave inverter outputs true sine wave alternating current without electromagnetic pollution, which is the same or even better th...

How a UPS system works with a Generator

Sep , 19 2022

As weather extremes and storms increase, power outages are likely to continue to rise. According to the U.S. Energy Information Administration, U.S. customers experienced an average of nearly six hours of power interruptions in 2018. If you have invested in a generator, you’ve prepared for when a storm hits, right? Almost. Even with a generator, you still need a battery backup, also known as an Un...

Failure causes of lithium battery- Failure during charging and discharging

Oct , 08 2022

The battery is often overcharged in the process of use. Relatively speaking, the overdischarge situation is less. The heat released during the overcharge or overdischarge process is easy to accumulate inside the battery, which will further increase the battery temperature. , affecting the service life of the battery and increasing the possibility of the battery catching fire or exploding. Even und...

What is round trip efficiency and response time for Energy storage solution?

Oct , 31 2022

Round-Trip Efficiency Round-trip efficiency takes into consideration energy losses from power conversions and parasitic loads (e.g., electronics, heating and cooling, and pumping) associated with operating the energy storage system. This metric is a key determinant of the cost-effectiveness of energy storage technologies. Among energy storage options, compressed-air energy storage (CAES) has the l...

Major Interconnection Issues for Energy storage solution

Oct , 31 2022

Major Interconnection Issues Generally, DG-based power systems can operate in independent or stand-alone and grid-connected modes. In fact, in the first mode, the capacity of a DG unit is selected only based on the load requirements. But, in the latter case, this constraint is not determinant. Although the grid-connected operation mode usually is preferred due to the bilateral energy exchanges, th...
