Boosting Voltage from a Wind Turbine: Tips and Tricks

AI Thread Summary
To boost a variable 1V output from a wind turbine to a constant 12V, a 1:10 transformer can be used to step up the AC voltage to approximately 10V. Following this, a rectifier setup with a diode bridge and a smoothing capacitor can convert the voltage to around 12V DC, accounting for diode voltage drops. Concerns were raised about the low output voltage, suggesting potential faults or incorrect measurement methods. It's important to ensure that the correct component type is being measured, as confusion between AC and DC readings could lead to misinterpretation of the turbine's performance. Proper design and measurement techniques are crucial for achieving the desired voltage boost effectively.

If I have a variable voltage coming from a wind turbine of about 1 V, how can I step it up, at a low cost, to a constant 12 V? Thanks

You could use a 1:10 transformer to turn the variable (AC) voltage from 1V to 10V and then use a rectifier (diode bridge + smoothing capacitor) to transform that into [10*sqrt(2) - 2*diode turn-on voltage drop] V, which would be somewhere around 12V (DC) depending on how you design it.
 
Is this alternator home made? The output seems to be a very low voltage and I wonder why. Could there be a fault?
(Or are you measuring the DC component when you should be measuring the AC component?)
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
