Energy Harvesting with Electro Magnetic Micro Generator

Energy Harvesting (EH) from human or environmental sources has proven to be an effective alternative or complement for battery charging or other uses.

 As light, thermal, mechanical and RF are major sources in EH and among them, mechanical energy from wind, waves, vibrations, etc. is commonly existed in our daily life.

In this new thread the energy will be harvested by using micro generators. This research project addresses the development of a unique EH circuit capable of fulfilling our needs.

The circuit proposed here that I was going to build'


 

 

For a very low power circuit, a very important point to check for this type of circuit is transfer theorem which states that the maximum power is transferred to the load when the resistance of the source is equal to the resistance of the charge.
Thus the type of conduction will be of great importance, as we know I will have to choose between DCM, BCM and CCM

Hello Jagau,

Two questions:

  1. What does BCM means ?
  2. Is L1 an coil / inductor ? If yes, where is the load ?

For DCM and CCM I found this:

The Difference between CCM and DCM Explained

More specific, current and voltage waveforms:

For BCM I found some references where it's a body control module in automotive electronics, not sure if it's the same with the one from your post.

Fighter

Hi fighter
DCM discontinuous conduction mode
BCM boundary conduction mode, just between the two.
CCM continuous condition mode

These are abbreviations usually used in DC-DC and AC-DC converters, you just have to find the right one that does according to the input versus output impedances.

Yes L1 is the coil i will harvest energy with the help of two mosfet.

For the schematic for the moment ther is no load but with time will have to adjust according to the impedances that I will have experienced. I used split capacitor charging model with a bigger onein parallel to attenuate the ripple.
We are at the very beginning and there is a lot of experimentation to do yet, thank you for your interest.

An interesting topic, as in the patent application of N Tesla a metallic sheet is used as receiver, it would be a good point of research to test various materials and surfaces . Ther might be a kind of photoelectric effect involved, converting certain radiation. Regarding the schematic, it could be convenient to bypass the bodydiodes of the MOSFETs with shottky or similar diodes? Vidura.

Hi Vidura
Yes There is a lot of research in this direction these days, just a small chart on RF emissions to see all the energy around us.

tab
It's amazing to see the density of energy that surrounds us, radio, TV, cellular. etc. with the distance the density power.

Small update of the microgenerator.
Is still running since November 1, 2021, almost 1 year
Today is rainy weather and at these times, about 100 blinks per minute,  it blinks much faster and at night much slower compared to daytime. In fact a lot of energy recovered from the ambient.

No batteries just a capacitor which recharges from the environment and discharges into an LED like Tesla patent 685957, a great success. I could say it's an eternal blinker.

Proof that there is a lot of hidden energy in the environment around us, as Don Smith said.

Very nice ☺️

When raining there is higher electricity in the atmosphere.

Yes, it's eternal 100%, the only thing which could stop it is an component becoming malfunctional because of aging but that will probably happen within 10-15 years.

It's very inspiring to have a continuously-running device like this or like my water-based device, it permanently reminds you about the endless possibilities opened by the ZPE technologies using the "ocean of energy" which is all around us...

Fighter

The circuit for those who want to do it.

If you need advice, just ask, I'll be happy to help you.

Hello

Jagau have you tried replacing the metallic part with a 24~ meter antenna ?

The aerial used is about 200 feet long and is about 80 feet above the ground: the wire is a copper cable approximately a fourth inch in diameter, and well insulated. The ground is the water pipe in the basement of Dr Moray's home.

Hi Gandalf

There is an huge potential difference between the ionosphere and Earth's surface in Kv range. Just imagine if i put a little 3 volts LED on this, probably burned instantly.

The energy network that surrounds us is more stable, that's what I'm working on right now, but others could try your proposal, it's still achievable but with a lot of height it becomes complicated.
