Hello on the above part number i need to design a 3_phase current share to balance all three INVERTERS in /of voltage and current.
Now since the UC3907 was intended for DC vol/cur and my application is for INVERTERS AC vol/cur output.
What I think I need to do is first have a small transformer across the output of the inverter sec winding this I will rectify and have a DC vol for the vcc pin and this will be a regulated voltage for stability. Now for the ac voltage and current I will use rams to DC converter so I will have a DC voltage for the two section so it will monitor the vol / cur correctly so I will have a feedback signal from the part and all three UC3907 will have a diode from each section and the output of all three diodes tied together the diode signal will go to the error amp of the unit where the main error amp of the INVERTERS will have a diode as well so all three outputs are blocked by the diode. Now each unit will have it own UC3907 designed within the unit so all I need to do is all two jumpers one from the error out pin of the UC3907 and one that will tie the share bus together. Let me no what you think about this send me a email direct
Thanks
