I have finished the first steps that included mapping the circuit boards, getting the unit to run and test it with a few simple test and finding out which input and outputs the module have. Schematics and further experiments with f.ex. scintillation crystals are set for the near future and will be announced when they […]

I had the chance to take this Eaton Powerware 30 kVA / 27 kW (9355-30-N-7-2x9Ah) uninterrupted power supply apart to look for parts worth salvaging for future reuse in other projects. Looking up the type on the Eaton website we learn that it is a UPS using double conversion topology that provides isolation from all

I picked up two of there 5.5kW frequency inverters from a scrap yard. Both assumed to be thrown out due to malfunction. I took them home to dismantle them for parts to use in other projects. First we have the front and two stickers, one with specifications and the other with end of life information.

I added a new online calculator that will help you do the calculations for IGBT gate drive. It is useful for continues wave operation and has a optional input and output for use with Tesla coils like DRSSTCs. Check it out! http://kaizerpowerelectronics.dk/calculators/igbt-gate-drive-calculator/ Learn how to build your own Tesla coil and how to make it

First light test and unfortunately under horrible conditions. We finished all the cabling and other small parts, bits and missing stuff in a days hectic work. In fact, by day, I mean that it that lasted all into the night. So we missed the opportunity of testing in darkness. There was no tuning performed, input

Read all about the small VTTC here: https://kaizerpowerelectronics.dk/tesla-coils/kaizer-vttc-iii/ I found some old notes and a short video of a quick lash up vacuum tube tesla coil I made in a single day. I wrote the details down and drew a schematic for those interested in using small PL output tubes for similar VTTCs.

I found a little time to put together the pictures, measurements and results of a solar panel I built from broken solar cells for sale on ebay. Not exactly a breakthrough in solar panel development, but more an eye opener on DIY solar panels. It might not always be a cheaper or better choice to
