Hi all,
We have a small 5KW genset the schematic is as shown in the attachment. Our conversation revolves around the exitation connections to the bridge rectifier.
Two sources of excitation are identified. One, the voltage reference from the alternator output through the choke to the bridge rectifier. The other , the current reference from the current transformer to the same point.
The two sources are in parallel and will be at different voltage levels depending upon the alternator load. This doesn't seem like a good idea and should give rise to circulating currents in the lesser voltage system. Is this how it is designed or are we missing something?
Explanations or ideas please.
