Power Electronics will play a key role in this paradigm shift to more renewable electrical energy and higher energy efficiency in multiple applications including transportation. In electrical energy generation a major shift to renewables as sources of future electrical energy will happen. The political institutions world-wide have the responsibility to create the boundary conditions to accelerate...
This paper analyzes different power supply architectures with the objective of mitigating efficiency and availability deficiencies in air conditioning systems for telecom and IT applications. The paper emphasizes the importance of running air conditioners with variable speed drives and discusses why DC power architectures seem to be more adequate than those with AC power. The analysis shows that well-configured...
This paper presents a very brief review on the energy loss development so far. There are lots of advancements in terms of generation, distribution, transmission and utilization. Also energy loss could also be reduced through training so the users know the limitation of the devices used.
Summary form only given. Many of us are aware of the impact of mobile and consumer era SOCs on Low Power Design. What is less known is the impact of proliferation in volumes unimaginable ever before and how that impacts already scarce energy resources in various parts of the world. Today, the energy consumption of installed semiconductors is responsible for more CO2 emissions than the entire airlines...
In a typical data center, less than half the energy consumed is delivered to the compute load, with the rest lost in power conversion, distribution and cooling. Traditionally power distribution is at 400/480 V AC in data centers and at -48 V DC in telco facilities. Higher voltage DC has been proposed as an energy efficient distribution option for both types of facilities, and this paper presents an...
The following topics are dealt: renewable energy and energy efficiency; computer applications in power systems; power system operation and planning; power electronics and drives; power transmission and distribution.
With the gaining of popularity of concept of distribution generation (DG) and sustainable development, DG with renewable energy (RE) sources is one of the possible ways for building energy supply in the future. The current "DC-AC-DC" route from DG to DC loads via inverters may not be rational from the viewpoint of system simplicity and energy efficiency, a review on the current electrical...
