Even show cumulative amount of energy consumed by the driven circuit. Doesn’t have to be quick. More than likely this would mean a custom transformer so instead I plan to use three off-the-shelf torroidal transformers.
The Raspberry Pi controls the mains supply to the transformers using some solid state relays. At this point the capacitor current is greatly reduced as the capacitors have charged. When the button is pressed again this just notifies the Raspberry Pi a shutdown was requested and the Pi initiates a shutdown before finally signalling its supply to turn it off. The GUI is really dataasheet. If you decide to do something with my design consider buying me a beer!
Thanks again for those well made projects. I may re-visit this. The user interface is dtasheet using the Kivy Pi Python toolkit. I was initially using Welwyn wire power resistors but had lots of problems with the readings wandering as the resistor heated up. There is a small overshoot when the voltage is set or irfp404n it comes out of current limit.

This page provides an outline of the project and links to the various blog posts that I wrote as I was developing the power supply. Big high VA transformers are expensive and to accommodate multiple channels the transformer would have to have lots of taps. In addition the circuit switches transformer taps daatasheet different voltage ranges. It’s pretty reliable and powerful Very precise Low noise Relatively quick to respond to load transients.
See here for the first attempt. Lab Power Supply Project. Digitally settable output voltage. It’s small enough not to be a concert mVs The banana sockets have enough resistance that the measurement of the voltage at the back of the terminals creates a few mV of error at the front of the terminals. Displayed current, measured output voltage and power output.
All the schematics and software are available on Github here https: There is lots more that could be done here. The specs I ended up with were: In the end I decided to manually wind an additional winding onto the transformers and run this is series with the output winding. So i was wondering if the schematics made with kicad were available to download.

The problem with this circuit is it generates considerable noise as it switches at the point where the current is maximal. I’m also looking at your dummy loadsurely you know what you’re doing. This means a decent graphical display is required To have an Ethernet interface. Most of this is not complete but the architecture of the implementation datqsheet I can support all of this in the future.
Transformer Tap Switching, Gate Bias supply and auxiliary supplies. Yeha datashfet just googled it and i’ve found it on github it’s strange that this psu isn’t mentioned in forums because it could be the rival to an “industrial ” power supply.

There is a bi-colour LED that indicates the power state of the whole system and a momentary switch dataseet user uses to turn on or off the entire system. I’ve another questionon the voltage and cjrrent control schematics P1 the 4 pin connector at the end, as far as i can understand that is the output’ but i cant uderstand what the voltage control op amp is measuring because its input are tied to earth. Hi first of all i must say that this is irrfp044n real power supply and probably one of the most complete on the internet.
In addition this circuit switches in a resistor temporarily to reduce the in-rush created by the transformers and then a second SSR short circuits the limiting resistor. In addition to the voltage control loop the circuit has differential voltage measurement from the output terminals to minimise the voltage differences due to internal resistances of tracks etc.
In my version of this circuit I changed the voltage control to be a set level above the desired output and added circuitry to ensure the voltage didn’t get thrown around too much if the supply goes into current limit mode.
