Your wiring cannot work because it contains no oscillator. If you publish something, let it be fully functional. There is a diagram of your converter in the video that you can watch via the link. Since it does not contain the already mentioned oscillator, it will not work. In the video, I also included a diagram of the inverter that I used for a while as a backup source for the circulation pump. With one pair of MJ15003 it is possible to use a load of 150w for a short time 200W, by parallel connection the power can be increased as needed. Today, however, I would no longer do this, because the connection does not include feedback, as a result of which the output voltage fluctuates according to the power input of the connected load. ru-vid.comjHleGJQ1860
