In this video I rebuild one of the Tesla coils with IGBT bricks instead of TO-247 devices. I am done with small transistors that can not outlive my abuse. With the new 2MBI50N-120 based inverter we can once again do the static load test and adjust phase lead compensation on the Tesla coil. This is […]

In this video I identify the root cause of the IGBT failures, to a wrong gate driver IC. With the correct gate driver IC, full-bridges repaired with tested IGBTs, we can finally finish the static load test and adjust phase lead compensation on the Tesla coil. This is the 5th article / video in the

This article and video focuses on full mains power startup, secondary coil terminations and connections, adding a new soft start module to the mains input for dealing with high inrush current and blowing the full bridge of IGBTs up completely. This is the 5th article / video in the series of designing and building a
This article and video focusses on configuring and validating the Universal Driver (UD2.9) functions and reforming the DC bus capacitors. Starting up a new electronics circuit can be done with various degrees of precaution. The easy way would be to apply full voltage and all inputs / outputs connected and see that the circuit behaves

In this video we put together the components, found in part 1, that is needed to build the DRSSTC design that was done in 10’ish minutes. This video focusses on how good looking construction can be done with simple tools. No 3D printer or expensive tools are needed. Imagination and craftmanship is enough to get

In this test and teardown video, we will learn about the construction of a high power contactor, the difference between AC-1 and AC-3 ratings and enjoy the lovely sound of a contactor closing and breaking! Compare it to this vintage ASEA 630 A / 440 kW contactor: https://www.youtube.com/watch?v=KTbE3G8mqis The AF265-40-11-13 is a 4 pole –

The primary goal of this video, is to find the components needed to build the DRSSTC design that was done in 10’ish minutes. The parts are either bought online, like the printed circuit boards, primary / secondary coil and topload. Other parts are found from my boxes of teardown / recycled materials, like the IGBTs,
