Magnetic levitation is used to float everything from lightbulbs to trains, with varying levels of success, but usually it requires a power source. Now, scientists in Japan have developed a way to make ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

All life depends upon energy from the sun to exist. Directly or indirectly, the sun is the source of all energy on our planet in the form of fire, water, and wind. Because of the Industrial Revolution ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...
