Today, the development of power generation from renewable sources is an effort to maximize the share of total energy consumption. Big source of energy in solar and wind power plants are mostly connected to the distribution network and supply the energy only if it produces (solar power station produced during the day and wind power station produced when is a wind acceptable). For this reason, the energy...
Many design objectives drive airplane development. One main driver is the reduction of aircraft weight, while retaining safety, function and performance. As extensive measurement campaigns have revealed, weight can be saved, as the electrical network exhibits low utilisation of the given network capacities. This is driven by requirements to be met, coincidence effects, and unexpectedly low system...
Cell phone battery life has been a fundamental design consideration ever since the first mobile devices were introduced in the 1970's. When mobile services were restricted to voice, the problem from a system design perspective often boiled down to finding best of breed components (e.g. amplifiers, signal processors, etc.) that optimized power while not sacrificing size. However, today's cell phones...
In recent years, there have been increased interests and demands on electrical vehicles (EVs) as one of the green technologies. In order to overcome the critical issues of the batteries on EV introduction, KAIST introduced the new concept of electric charging method, called OLEV® (On-Line Electric Vehicle). OLEV® technology utilizes the inductive power transmission principal, so that the EV can be...
