ENERGY AMPLIFICATION

[Dave45]

Dave, think of an inductor as a flywheel:  As the flywheel resists changes in speed, an inductor resists changes in current flow.  The battery is a needed source of EMF in order to establish a current flow in the inductor.  Once the current is established, the inductor resists increasing or decreasing that current.   As the transistor turns off reducing the current through it, the inductor BEMF causes the voltage on the switched side of the inductor to swing away from the battery voltage that is on the other side of the transistor.  The voltage keeps moving until the diode passes the balance of the inductor current no longer being carried by the transistor.  The now reverse voltage across the inductor acts to reduce the current.  When the transistor turns back on, the coil again resists changes in current, and the current only increases at a rate proportional to the voltage difference across the inductor:  battery voltage to load voltage.

I guess one could look at it like that but I would rather understand whats really happening, its the rise and fall of the magnetic field.

Dave viewing inductance as an analog to inertial mass produces accurate results.  What's really happening is that magnetic fields resist change in flux density:  B just as inertial mass resists changes in velocity.  The differential equations that apply to both are identical.

spin up and spin down of the gyroscopic mass (wheel)


a small capacitance like a open switch or a blocking diode that prevents the flow will have a small current storage, but increase the voltage rapidly... like a short strong spring catching the wheel... which has 100% (resilience?) ... which store all the energy and then dump it back into the wheel in a new acceleration... Yes; at this point current reverses... but that's after the field has totally collapsed (wheel stopped)
a large capacitance like a capacitor of any size more than a wire; lots of current will continue to flow but the overall voltage will be low...


I guess the spring K constant is more related to a power... when I started to mention voltage and current it started to fall apart but it doesn't matter cause the product is the same.

Misunderstanding of these facts is exactly why there are people who think a Don Smith/Kampandze or even a mechanical analog in the Chas Campbell can actually produce watts. In reality the Don Smith/Kampandze are just capable of being very efficient transformers. I don't believe either of those individuals are seamstress btw i just think they are deluded.
