It’s an easy to build high voltage power supply that interfaces with an Arduino. After harvesting a flyback from the power board of a CRT, [Andrew Moser] added a new primary coil to the transformer.

In my example the whole circuitry is powered from a 9V battery and I use a small 12V fan, but you should use a 9V or 6V. If you want to use higher currents then replace the BC547 (100mA maximum ...

A regular halogen lamp 12V transformer takes care of the heater power supply for all the tubes, and a second, smaller 12V transformer is wired backwards to provide the 300V needed for the plate ...

I am an American living in Switzerland and have no problems with most of my equipment running off a 240-120V transformer. Everything except some electronic equipment which also has its own 12V ...

The 12V LiPo battery is first stepped up to 120V using a micro-inverter, then stepped up to 1550V through a transformer before being rectified. The high voltage rectifier gets quite hot so a ...

Learn about a successful solution using Bourns HCTSM8 transformers and TI SN6501 drivers to isolate a 12 V bus rail in a communications system or power supply for switching IGBTs. Continue Reading ...
