<b>Wind turbine</b> design is the process of defining the form and specifications of a 
<b>wind turbine</b> to ... In some cases, especially when turbines are sited offshore, the 
<b>DC</b> energy will be transmitted from the turbine to a central (onshore) inverter for ... 
The generator in a <b>wind turbine</b> produces alternating current (<b>AC</b>) electricity. One approach to allowing <b>wind turbine</b> speed to vary is to accept whatever 
frequency the generator produces, convert it to <b>DC</b>, and then convert it to <b>AC</b> at 
the&nbsp;... Power electronics is the application of solid-state electronics to the control and 
conversion of ... An <b>AC</b>/<b>DC</b> converter (rectifier) is the most typical power 
electronics device found in ... A power optimizer is a type of <b>DC</b>/<b>DC</b> converter 
developed to maximize the energy harvest from solar photovoltaic or <b>wind turbine</b> 
systems. A submarine power cable is a transmission cable for carrying electric power 
below the surface ... 1.1 Conductor; 1.2 Insulation; 1.3 Armoring; 1.4 <b>AC or DC</b> ... 
Modern three-core cables (e.g. for the connection of offshore <b>wind turbines</b>) often
&nbsp;... In electricity generation, a generator is a device that converts motive power (
mechanical energy) into electrical power for use in an external circuit. Sources of 
mechanical energy include steam turbines, gas turbines, water turbines, internal 
combustion engines, <b>wind turbines</b> and ... However many early uses of electricity 
required direct current (<b>DC</b>). A grid-tie inverter converts direct current (<b>DC</b>) into an alternating current (<b>AC</b>) 
suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz 
or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power 
generators: solar panel, <b>wind turbine</b>, hydro-electric, and the&nbsp;... A high-voltage, direct current (HVDC) electric <b>power</b> transmission system uses 
direct current for ... Practical conversion of <b>power</b> between <b>AC</b> and <b>DC</b> became 
possible with the development of <b>power</b> electronics ... HVDC overhead lines for 
onshore <b>wind</b> integration projects and HVDC cables for offshore projects have 
been&nbsp;... A <b>power</b> station, also referred to as a <b>power</b> plant and sometimes generating 
station or ... Because of the <b>DC</b> distribution, the service area was small, limited by 
voltage drop in the feeders. In 1886 ... High-voltage <b>AC</b> transmission allowed 
hydroelectric <b>power</b> to be conveniently moved from distant waterfalls to city 
markets. An induction generator or asynchronous generator is a type of alternating current 
(<b>AC</b>) ... An induction machine can be started by charging the capacitors, with a 
<b>DC</b> source, while the generator is turning typically at or above generating speeds
. ... Induction generators are often used in <b>wind turbines</b> and some micro hydro&nbsp;... A <b>DC</b>-to-<b>DC</b> converter is an electronic circuit or electromechanical device that 
converts a source of direct current (<b>DC</b>) from one voltage level to another. It is a 
type of electric <b>power</b> converter. <b>Power</b> levels range from very low (small 
batteries) to very high (high-voltage ... For example, to convert the <b>DC power</b> 
supply to high-frequency <b>AC</b>, use a&nbsp;...
