Power Factor Correction Equipment : advantages and disadvantages

Normally, the power factor of the whole load on a large generating station is in the region of 0•8 to 0•9. However, sometimes it is lower and in such cases it is generally desirable to take special steps to improve the power factor. This can be achieved by a particular equipment, just as this article explains.

Energy efficient lighting : CFL vs LED

Two of the most common such electrical bulbs are the Light Emitting Diode (LED) bulb and Compact Fluorescent Light (CFL) bulb. These new-tech bulbs are designed to replace the incandescent bulb in form and function but with a much improved efficiency of converting electrical energy to light. However the use of any of the two has its own pros and cons.

Faults in Electrical Systems (back to basics)

We all are familiar and encountered at least once the phenomenon of fault occurrence in electrical system. A power system failure across the town that happened due to a storm breakout or an internal equipment fault that disrupted your local power supply these are all essentially the cases of faults in electrical systems. Through this article we tried to examine this phenomenon in little more detail.

Generator Ratings (back to basics)

When an Electrical Engineer is in field dealing with generators, then it’s very important for him to know the rating of under process generator otherwise he may cause a great loss. This article goes back to basics.

Multilevel Inverter Topologies

Owing to the recent popularity and immense industrial usage of multilevel inverters, a lot of research is going on in the field of multilevel inverter topologies. All these topologies have various applications along with their inherent limitations. There are two methods of controlling multilevel inverters: PWM Control (allows variations in output voltage) and Line Frequency Control (does not allow variation in output voltage)

Which of the topologies is the best depends, upon place where you use it and you requirements. There are many types of multi-level inverters, designed according to different applications and their uses.

Effective monitoring of AC motors

When it comes to the usage of home appliances, one of the most important areas is that of short circuits. There are a number of reasons behind this issue, but the important point is that the issues can be resolved by opting for some measures.

How to manage AC motors in an effective way? The answers are in this article. Did it help you?

Cascaded H-bridge multilevel inverters

One of the basic and well-known topologies among all multilevel inverters is Cascaded H-Bridge Multilevel Inverter. It can be used for both single and three phase conversion. It uses H-Bridge including switches and diodes.

Now that you know multilevel inverters topologies, check what we have to say about Cascaded H-bridge multilevel inverters. Which features? Which advantages?
