Re: Neutral spike

Hello to all those interested, I have now built a push-pull inverter for the transverter anti-drive to drive it. From 37 Hz 650Hz is fully adjustable and the pulse width.
A simple square wave signal is generated and sent. It works wonderfully. The interference is a problem when switching 350V peaks. I have now wrapped all power lines with aluminum foil and this one-sided grounded. The boards I will install in an aluminum housing and also this ground, the disturbances are almost all gone. By shielding, the energy is no longer emitted and remains in the lines apparently, since the shielding, the high-power mosfets are very hot although they are used at most 10%. The cut-off voltage at the drain increases in the kilovolt range when the transverter is connected. The complete line to Transverter is also shielded. I now wanted to build an Energy Recovery Snubber to recycle that energy. First test show that you can drive the transverter so much more efficient. I have to build this inverter even more reliable or change.
Best regards
