Hello,
Working on design - inverter for 3 phase induced motor 380VAC x 3
I am using IGBT module (rectifier + 6 transistor) that convert the 3 phase to ~537.4VDC = 380 x 1.414
I need from that voltage 537.4VDC create lower voltage for the control section - 15V + 3.3V Isolated
one option is to use flyback trasnformer with multioutput with isolation
other option is to take one of the phase (220VAC) and rectifier it and create DC voltage
My input to system is just 3 wire (L1,L2,L3) only the 3 phase
to recticifier the 220VAC I need neutral (which is not in my system)
How can I "create" neutral from the 3 phase - or I must use neutarl form the socket (which I havn't -or not connected)
Thanks for your time
Mayer
