I'm calling it the Royal Oscillator.
Can I use this to power a Cockroft-Walton adder?
Keep the mat's and sling the wife out.
The voltage divider ratio is not confirmed by the oscilloscope because you can't add reactance and resistance in the scalar form as they are perpendicular to each other. So the formula for the voltage divider that involves a capacitor is a bit more complex, it involves a ration in its vector form.
Where is WALES
Is the metal pin for the oscilloscope on the blue capacitor side soldered to one off the capacitor pin?
Could the falling current be caused by the very temperature dependent resistance of the bulbs?
Your wife is prescient!
Since you mention the Brexit with your dinner maps, do you have any idea what's going to happen with these Chinese stores which have warehouses in the UK?
You also seem to oder much stuff from China too. It would be a pity if we had to pay custom taxes for things we ordered from continental Europe for stuff from the Hobbyking, Banggood, etc. UK warehouses. If there won't be free trade between the UK and the EU it doesn't matter (moneywise) if I oder things directly from China or from the UK. However it takes about 3-4 weeks longer to ship things from China even if Shenzhen is almost 9000km more away than London.
No reason to drive the circuit as sinewave, modified sine would be much more efficient. But why balance ? much better just charging each cell independently.
This is not a capacitor. It is a surge suppressor that is typically placed across the mains input to suppress spikes.
so do you search through your own trash to see what your wife has tossed out?
the cap getting warm shouldnt be there,as class y metal film type is usually to chassis for emi filtering. . .I,m surprised it hasnt croked it.!. the dc- ac lamp inverter circuits typically use polypropylene caps in the output to limit the current to the fluoro tube. , but not cheap,so to save on cost ,this fellow got the job.
Its an safety cap, its designed to be connected to Earth hence the Y, it is however NOT designed to be in parallel with the output, therefor it gets warm.
julien are you going to assemble the x carve
This may help, I found it on a different ebay listing:
First: can not be used in: iron core transformer (including the motor category)!
Second: the output of sub ABCD multiple combinations, each has its advantages, such as:
A plus C for output: the output of this circuit with power overload protection.
D plus C for the output: the output of the direct hybrid (electromagnetic valve relay capacitor charging lightning protection equipment and socket outlets can be normal use) of the dual template direct hybrid compatibility of the best.
A and B as output: the output specifically for resistance capacitance step-down drive (Nightlight resistance capacitance LED lamp 110V AC electrical appliance) these two kinds of products, then can not be used.
Third: double mode board this three way can be used at the same time, the total power is not more than 35W.
Dual template: 3V-14V battery can be turned into 220V and 110V alternating current and 220V DC power.
Output voltage: AC AC100V DC220V AC220V power output rate 0.1W-26W
If the input voltage is 3V, the output is 1W-3W (automatic variable power, according to the load and meaning)
If the input voltage is 5V, the output is 1W-5W (automatic variable power, according to the load and meaning)
If the input voltage is 8V, the output is 1W-10W (automatic variable power, according to the load and meaning)
If the input voltage is 10V output is 1W-15W (automatic variable power, according to the load and meaning)
If the input voltage is 11V output is 1W-18W (automatic variable power, according to the load and meaning)
If the input voltage is 12V output is 1W-26W (automatic variable power, according to the load and meaning)
If the input voltage is 13V output is 1W-28W (automatic variable power, according to the load and meaning)
If the input voltage is 14V output is 1W-35W (automatic variable power, according to the load and meaning)
The product is high frequency current, the common universal meter can not test the voltage of the (dual template of the DC hybrid can be tested after the load), the single template needs to use a professional high-frequency universal meter to test the output voltage. You use different brands of universal table test out the voltage is not the same, there is a gap between the. There are customers to reflect the universal meter test out of the voltage is too high, but also some customers reflect the test out of the voltage is too low, which is different models tested different results. In the use of incompatible products will not high voltage. Can consult the owner before use.
The actual voltage of this product is in the 210V~240v to meet the electrical input safety voltage.
The dual template of the self loss power control and then 0.3~0.5W between, extremely power saving,
That capacitor is working its ass off… I'm truly surprised it works as well as it does.
Thanks for showing us the waveforms on the load- I was curious what it looked like with the cap.
I curious how it would work driving a 240volt 10 or 25w ish fridge lamp or similar as it was intended and what is efficiency and output wave would look like. It should easily drive a CFL. As some others have said the capacitor should not be dissipating energy in that circuit, I'm wondering if the very low impedance load adds to the issues.
