Hi, everyone. I came across with a bit strange to me case. System consists of :
1) three phase transformer(secondary 560Vac);
2) Input line reactor;
3) Three phase rectifier;
Measurements of the output of rectifier showing around 1200 Vdc. As I mentioned above the input Voltage is 560Vac. What could it be? Could be some affect of damaged line reactor?
And the AC voltage on DC bus is around 120Vac. Any suggestions?
Thanks
