Answer Posted / rohan k trivedo
simply we can understand vfd by the below relation
N= 120f/p
so in vfd speed will be controlled with the change in
frequancy. and frequancy can be changed by the thyristor
control pannel.

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.
