A single phase voltage source inverter is feeding a purely inductive load as shown in the figure.

The inverter is operated at $$50$$ $$Hz$$ in $${180^0}$$ square wave mode. Assume that the load current does not have any $$dc$$ component. The peak value of the inductor current $${i_0}$$ will be

A $$3$$ - phase voltage source Inverter is operated in $${180^ \circ }$$ conduction mode. Which one of the following statements is true?

In the circuit shown in the figure, the switch is operated at a duty cycle of $$0.5.$$ A large capacitor current is connected across the load. The inductor current is assumed to be continuous.

The average voltage across the load and the average current through the diode will respectively be

A three phase fully controlled bridge converter is feeding a load drawing a constant and ripple free load current of $$10$$ $$A$$ at a firing angle of $${30^ \circ }.$$ The approximate Total Harmonic Distortion $$(\% \,\,THD)$$ and $$r.m.s$$ value of fundamental component of the input current will respectively be
