While we had the box open for removing the real-time current control, as you can see in the previous post, I did a walk through of how the coil is put together and what parts have been used. Learn how to build your own Tesla coil and how to make it play music through a […]

The real-time current control (RTC) that can found in some IGBT modules is a protection against short circuits in f.ex. motor drives where they could have been used. The conditions on which the RTC acts is however sharing area with using IGBT bricks in Tesla coils, as the RTC will never interact while operating the

After cutting out the bonding wires to the RTC circuit of the CM600DU-24FA IGBT bricks, which we thought could be one of the reasons that we were not able to trip the 1500 A OCD setting, we had a short test run to witness performance. I will do a video with more details of the real-time
