I am trying to implement a PFC controller to AC/DC converter stage, but I have some problems to get the current feedback correctly so the output is more steady state. Also, the waveform have transients in the beginning, it is possible to reduce these transients?
I have connected a transistor...
The thing is, I was trying to regulate a 220V-9V to 5 volt. I did it though. Everything was right.I was trying to make a dark sensor with NOT gate
()
The settings are good. But it wasn't working fine with the AC to DC adapter.( It is working fine with a battery like the video). The thing is...
Hi all,
at the moment I'm trying to amplify an AUX-Signal with a 12V DC supply
voltage. I tried die setup from here as u can see in the picture below.
But all I get is just an annoying noise sounding horrible.
For the amplifier I used both the CA3240EZ and the OPA134PA.
Maybe my grounds are...
Hi guys! I'm trying to build a device to measure the electrical resistivity of a paste (cementitious materials) using Arduino Uno. Four steel probes are put inside the paste (jumper wires attached to them). Two outer probes apply AC signals (Square wave signals- Frequency 1 kHz- Voltage(peak to...
Hi,
Does anyone know of something to convert 240V mains to 15V DC at upto 2A? I want it to be as compact as possible.
I've been looking for PCB mounted modules but the price and size of them seems ridiculous. For example; Farnell sell a VTX-214-030-115 for £20.
You can buy a whole bench PSU...
