 29 Mar 2005 22:05 Inductor as Energy Storage/Transfer Element |

Hello,
How an Inductor is used as Energy transfer/storage element? Can any one explain usage of Inductor(along with current/voltage waveforms wrt time) for transfer of energy between 2 voltage sources?
Regards,
Chanchal

Hi,
if you apply a voltage on the leads of an inductor. The current starts to flow through it. The current will ramp linearly. It depends from the period of time in wich the voltage is applied to the inductor leads, to how much the current peak value will reach.
The equation is:
U = - L×(dI/dt)
Where L is the inductance of the inductor.
The energy accumulated in the inductor for this period is given with:
E = ½×L×Ip²
Where Ip is the peak value reached for the specified period of time.
Then you have different schematic variants how to transfer this stored energy to the output.

... and now you disconnect the leads from that charged inductor. Bwahahahahaaaaa!
The inductor tries to maintain the most recent current flow, but you've broken the circuit, so the resistance is suddenly enormously high. What happens? The inductor's voltage tries to jump to infinity, but the air breaks down, becomes conductive, and you get an arc. The inductor's stored energy has been rapidly converted to heat, light, sound, ozone, etc.
It's analogous to shorting out a charged capacitor.
Both can be fun. 
Both can damage equipment.

For some people the purpose of inductor is ... to generate sparks.
I was not giving direct instructions "how to".
I just sketch the principle of using the inductor for storage and transfer of energy.
I was thinking that somebody else will continue to form the complete picture, but...
There such "advanced" people that can not think hypothetically.
But they mark their territory like dogs ... they piss on everything.
