I have a slightly different version from Amazon . The strange thing is , i get 220v DC rectified out. But 0v on the AC. with my fluke meter. This makes little sense to me . As the DC part is rectified from the AC secondary. The only thing i can think of is my meter has so little load on the system that the primary is not oscillating? I have not shorted out the output capacitor. I want to use the module to convert a 240v hob ignitor to a 12v supply as part of a van conversion. No instructions on this version just Chinese. And it has diodes instead of a bridge rectifier. Your video helped make sense of the principle of the circuit. The amazon UK listing shows your board version. But get supplied a bad track layout version where the 220v side track runs very close to the input side.And is more like a maze than best route.
Can it run electric fan?
At the output of such things from aliexpress, there is a high-frequency impulse voltage, the multimeter does not see it and shows the wrong values of 500 or even 1000V. You need to use an oscilloscope for measurements.
can this be used to convert 18V Powertool battery to 230V AC for Phone charging?
I have just tested my unit (same one) and for 12VDC I get 265VAC out (no load) RMS. 4VDC in results in 80VAC RMS. Surpisingly, it produces output even down to a volt in. At 4V in and 300mA drawn, this is 1.2W. My bias load at 75VDC (ac rectified) draws 20mA, equalling 1.5W. So efficiency is around 80%, very good, however primary current will quickly rocket with increase secondary current. Good sinewave but clips under load, so radiates hash into audio gear. Needs to go in a shielded bix and leads.
TY Julian, just the info I needed. Cheers.
Pls link for that Digital Volt/current regulator
Thank you very much for your video.
would it not be better using a dc to dc boost board?
Se puede hacer 320v a 12v y de 5v ? Quiero saberlo pls
I'm looking for 10 volt DC input to a variable 10 volt to 20 volt AC output.
Currently in the fine print in the ad it says it can drive a 40W energy saving lamp. This is doing just what I thought it was going to do. It puts out about 6W without any cooling and that will indeed light up a 40W equivlient 6W LED bulb. I am not sure if this is a vagrancy of language translation or flat out deception as far as the specs go. It is a neat little module, but it is not what the average consumer would expect.
Can your meter even read 100khz+ AC?
did you ever use that royer oscillator for batteries lol
Good design 👍 but lacks efficiency, it also drifts the wave form causing more losses and unreliability. I would still prefer the 555 timer inverter but good info.
