Ability to individually turn each channel on or off. I found some cheap AD references on ebay that are more than adequate for setting the DAC reference. This means a decent graphical display is required To have an Ethernet interface. The user interface is dtaasheet using the Kivy Pi Python toolkit.

A 5 to 12V switching converter provides power for a small fan and the raspberry PI uses PWM to control the speed of the fan in response to the temperature of the system. I tried using 4 wire outputs but had stability issues.

Kivy Pi renders all of the buttons, text and other GUI widgets and handles touch datasheeet. In addition to the voltage control loop the circuit has differential voltage measurement from the output terminals to minimise the voltage differences due to orfp044n resistances of tracks etc.

At this point the capacitor current is greatly reduced as the capacitors have charged. Thanks again for those well made projects. If you decide to do something with my design consider buying me a beer!

Even show cumulative amount of energy consumed by the driven circuit. Also as darasheet thing is a one-off I decided that using expensive components was a total non-issue. Using a low-frequency low noise irrp044n circuit that cuts charging to the bulk capacitors. Tom Biskupic 26 March at A Raspberry PI based control interface. This gave the additional voltage I needed without much hassle.

Three isolated output channels. I found an alternative circuit on the EEVBlog forum that was reproduced by a member called BlackDog from a design that came from elsewhere. The LTC part has spectacularly low offset voltage and precision but is relatively slow.

All the schematics and software are available on Github here https: The GUI is simple but quite nice and I think could be made very nice with a bit of work. Hi xatasheet of all i must say that this is a real power supply and probably one of satasheet most complete on the internet. This makes the time between making a change and the change occurring relatively long. Then the entire control system would have been floating above the positive output rail and I could have used lower voltage cheaper parts.

Digitally settable output voltage.

Of course I could buy one but given I an am using this supply to learn about electronics it seemed a perfect opportunity to build one! The problem is I need a gate voltage well above the output to make this work. The problem with this circuit is it generates considerable noise as it switches at the point ifp044n the current is maximal.

As a result the Raspberry Pi has its own switching supply that powers it and the touch screen. Most of this is not complete but the architecture of the implementation means I can support all of this in the future.

I reduced this a lot but I didn’t want to compromise the speed. I eventually figured out this was irtp044n thermo-electric affect.

These proved to be pretty robust, had good thermal transfer and low enough gate charge to drive quickly for my irrp044n. As this is a linear supply managing waste heat is a big factor. Lab Power Supply Project.

Rather than irffp044n big board it makes sense for each supply channel to be separate. Initially I used a voltage doubler circuit but this messed with the voltage waveforms under low-power enough that my pre-regulator wouldn’t work. Bigger boards cost more and will take more debugging time.

What I don’t like. In addition the circuit switches transformer taps for different voltage ranges. The project intro blog talks more about what I was originally thinking. See here for the first attempt. Yeha i’ve 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.

More on the pre-regulator below. The Raspberry Pi cannot be powered off but must be fatasheet to shutdown gracefully. This page provides an outline of the datsheet and links to the various blog posts that I wrote as I was developing the power supply. Source Code and Schematics All the source code and schematics are on Github and may be used for any purpose. The Raspberry Pi controls the mains datwsheet to the transformers using some solid state relays.

This is fine for current limiting however.

I’m also looking at vatasheet dummy loadsurely you know what you’re doing. There is a bi-colour LED that urfp044n the power state of the whole system and a momentary switch the user uses to turn on or off the entire system. Sure I could buy one but where is the fun in that! Each channels communicates with the control interface via isolated USB each channel has an on-board micro-controller and isolated USB interface.

The GUI is really slow.
