In a Synchronous generator, Can AC voltage be used instead
of DC voltage in field winding of rotor to produce AC power?
Answer Posted / pavan
it can be used to generate ac current if the frequency of
the ac voltage supplied to the rotor and the frequency of
the rotation of the motor are different. but i am not sure
if the generated power will have only a single harmonic.

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
