The only uncommon part of the layout is the 1M Ohm Potentiometer and the two diodes. Spehro Pefhany k 4 Since this power supply is just a fun design for an upcoming nixie tube clock project of mine, I have the time to achieve ESE. Let me know what solution you have?

If you just reduce the anode voltage the current through the anode resistor drops and so does the cathode current. However, at high voltages i. But you may be interested to compare results if you knock this back to say 30pF or even exclude the snubber completely. I have since eliminated the current limiting resistors and redrawn the circuit.
555 Nixie Power Supply
This may be a topic for a future blog. Since the idea is to build something new, all the usual design are not the way.
That’s another reason I am trying to cover them here, so I can use this post as consolidated reference any time I need it. Let me know if you have any questions. This indicates that the stray magnetic fields were causing losses in the copper ground plane. The is driving another transistor that simply cuts off the voltage on the base of that “main” transistor.
Design power trees and estimate consumption of electronics designs. Design Notes – EEWeb. The biggest discovery during the verification was that core losses in the power inductor swamped all other losses.
The component values in the schematic allow a frequency variation between 3 – 8. One of the most popular solution for the square wave oscillator is by using the ubiquitous Tubes require high voltage to 5555. To ensure there was an adequate margin for the inductor energy i.
Nixie tube High-Voltage Power Supply
The bottom trace shows the same current through the FET. The IRF isn’t that big, and with a switching frequency on the order of 30kHz I’d be surprised if the gate current broke 1mA. In this circuit, the feedback is created by using a transistor to pull down on the control voltage node of thewhich reduces the upper switching threshold. Wise Clock 3 – Pong. February 3, Author: Known Problems so far: These losses are quite difficult to calculate.
It has a bigger effect on the frequency of the output pulses, but this isn’t relevant. This was obtained through both experimental and calculations nnixie.
Great article, I am enjoying what I am reading! Building Fleet, part 14 1 year ago. What I want from my power supply is to be able to drive a nixie clock, so more than 4 tubes. When these three items match, not only do you understand a system, but you have the best chance to optimize a better solution. This phase margin looks to be greater than 45 degrees. Most micro-B connectors have a 1.
