Managing the heat achieved by:. At this point the capacitor current is greatly reduced as the capacitors have charged. Even show cumulative amount of energy consumed by the driven circuit. More on the pre-regulator below. This means a decent graphical display is required To have an Ethernet interface.

Big high VA transformers are expensive and to accommodate multiple channels the transformer would have to have lots of taps. Tom Biskupic 26 March at Bigger boards cost more and will take more debugging time. 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: 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!

Ability to individually turn each channel on or off. I’m also looking at your dummy loadsurely you know what you’re doing. Then the entire control system would have been floating above the positive output rail and I could have used lower voltage cheaper parts.

Displayed current, measured output voltage and power output. Large heat-sinks Temperature controlled fan Use of MOSFETs as the pass element and pre-regulator switching element to reduce the dropout voltage of the regulator. I tried using 4 wire outputs but had stability issues. Transformer Tap Switching, Gate Bias supply and auxiliary supplies.

In addition the circuit switches transformer taps for different voltage ranges. I eventually figured out this was a thermo-electric affect.

In March I started designing a precision, low noise lab power supply. Happy to help answer any questions. 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.

IRFPN Datasheet PDF International Rectifier –

Hi first of all i must say that this is a real power supply and probably one of the most complete on the internet. More than likely this would mean a custom transformer so instead I plan to use three off-the-shelf torroidal transformers.

Rather than muck around with designing a custom front panel I decided just to use a nice big high-res touch screen. Lab Power Supply Project. I found an alternative circuit on the EEVBlog forum that was reproduced by a member called BlackDog from a design that came from elsewhere. It’s not the GUI itself but the fact that the system is polling three channels over relatively slow serial links.

Python code polls the state of each channel and updates the GUI. The project intro blog talks more about what I was originally thinking.

The datasheey with this circuit is it generates considerable noise as it switches at the point where the current is maximal. The user interface is built using the Kivy Pi Python toolkit. This doesn’t provide datsheet over the pre-regulator but does allow higher current output at lower voltages 4. It’s pretty reliable and powerful Very precise Low noise Relatively quick to respond to load transients. Sure I could buy one but where is irfp0044n fun in that! So In general what I’d like is to have two or three output channels and the ability to run two in dual tracking mode.

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. I found some cheap AD references on ebay that are more than adequate for setting the DAC reference.

See here for the first attempt. The GUI is really slow.
