Introduction I received a bare board and some of the SMD components for a OpenThereminV3. It is a semi-assembled kit that can be bought from Gaudi ( http://www.gaudi.ch/OpenTheremin/index.php?option=com_content&view=article&id=180&Itemid=115 ). The board I got was from a previous unsoldered kit where you have to buy all the components yourself. This totalled to another 35€ in parts as […]

In part 2 of the hacking series, I am doing measurements on the IGBT waveforms and voltage/current waveforms output form the quasi-resonant inverter. Part 2 of hacking the IKEA induction cooktop: https://kaizerpowerelectronics.dk/general-electronics/hacking-ikea-2kw-induction-hob/ Discussion of this project is on Highvoltageforum.net thread: https://highvoltageforum.net/index.php?topic=104.0

With the snubber capacitor calculator, you can calculate the needed snubber capacitance. The correct value is needed in order to protect your inverters IGBT/MOSFETs. Protect them from too high switching transients, depending on your busbar layout and stray inductance.

From one day to another this mini circuit breaker stopped working, I had been using it wrongly as a on/off switch and was wondering if there was a mechanism inside to disable it after too many on/off switches, as MCBs are only rated for a finite number of operations.

Since Martin from ctc-labs.de decided to close down his website, which was all written in German, I asked him for permission to translate and publish some of his content to keep it online and public for others to use. So here is the translated article about his small and simple analog circuit that can be

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
