Intruduction to Number Systems
Number systems provide the basis for conveying and quantifying information. Weather data, stocks, pagination of books, weights and measures - these are just a few examples of the use of numbers that affect our daily lives. For this purpose we find the decimal (or Arabic) number system to be reliable and easy to use. This system evolved presumably because early humans were equipped with a crude type of calculator, their 10 fingers.
DC Motors explained
There are several types of DC motors, including shunt, series, compound wound or stabilized shunt, permanent magnet, and brushless DC. The main differences between these types of motors revolve around how the electromagnetic fields are generated. For example, in a permanent magnet motor, the magnetic field in the stator is supplied by permanent magnets positioned just inside the frame of the motor.
Fraunhofer ISE develops highly compact UPS Inverter
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have developed a highly compact and efficient inverter for use in uninterruptible power supplies (UPS) for electrical devices. The demonstrator, which contains innovative silicon carbide components, was developed in cooperation with an industry partner and achieved an efficiency of 98.7 percent.

Arc fault protection system
Arc faults in switchgear installations release high amounts of energy, generating extreme heat and a considerable pressure wave. This leads to failure or complete destruction of the switchgear installations – and of course it also affects all systems and devices connected to them. This is why protection solutions are needed which enable the fast and reliable extinction of an arc fault – such as the DEHNshort system.

The History of the Electric Car
Introduced more than 100 years ago, electric cars are seeing a rise in popularity today for many of the same reasons they were first popular. Whether it’s a hybrid, plug-in hybrid or all-electric, the demand for electric drive vehicles will continue to climb as prices drop and consumers look for ways to save money at the pump.
