Is there a circuit which can give inductance without actually using a inductor ?

 

Yes it is possible. Those circuits are called gyrators and they simulate inductance.

Thanks man

They're pretty much standard equipment in those graphic-equaliser tone controls with a row of sliders on the front panel.

 

Note that they simulate inductance for small signal applications, like filters, but do not simulate the energy storage capability of a real inductor.

 

They would make terrible flyback circuits if you wanted an output higher than the power supply voltage.

 

Sure it depends on these things, just as the voltage of a power supply depends on the load. In theory it shouldn't, but in reality it does because the gas supply has an effective impedance (the valve only opens so far and the gas passage is only so big) and the line and meters have an impedance.

As you and Dick have noted if you want an alternative to the energy storage capacity of inductive magnetisem, you could always electrically drive a flywheel, connected to a generator, or heat a kettle, connected to a turbine-generator.

Somewhere I read that in one country they sealed up an abandoned salt mine and used surplus energy to fill it with compressed air. When there was no surplus, the compressed air was released into generator turbines.

 

How did we go from simulated inductors to high energy storage?
Did someone get on the wrong thread?

You pointed out that the gyrator circuit doesn't store energy like a real inductor.

I think the artificial inductor can be as simple as a single bipolar transistor, a capacitor and a few resistors - I've seen those in one or two guitar pedal schematics.

Well I was thinking more along the lines of the mJ of stored energy in a switching regulator inductor, not the MJ of energy needed for energy grid storage.
