Elektronika Daya discusses power electronics, which is the field that studies the use of electronic technology in converting electric power. Power electronics is needed because most electrical devices work inefficiently or cannot function using the available power sources. It also discusses various power electronic applications in power generation, transmission, distribution, transportation, industries, and home appliances. Some current challenges mentioned are voltage regulator modules for microprocessors and renewable energy power generation systems.

Scope
It is not possible to build practical computers, cell phones, personal data devices, cars, airplanes, industrial processes, and other everyday products without power electronics.
Alternative energy systems such as wind generators, solar power, fuel cells, and others require power electronics to function.
Technology advances such as electric and hybrid vehicles, laptop computers, microwave ovens, flat-panel displays, LED lighting, and hundreds of other innovations were not possible until advances in power electronics enabled their implementation.
Although no one can predict the future, it is certain that power electronics will be at the heart of fundamental energy innovations.
