(v) The RFI generated in a current-fed inverter is much lower than that
in voltage-fed inverters, since RFI is essentially generated by
changing currents and in a current-fed inverter the current is
substantially constant.
(vi) The current drawn from the supply in a current-fed inverter is much
smoother than that in a voltage-fed inverter, so that the filtering
requirements are also much less.
In spite of some of the advantages of current-fed inverters, voltage-fed
inverters continue to be used, since they are more versatile in a variety of
applications, and they are easier to control.
