A single - phase half controlled converter shown in the figure feeding power to highly inductive load. The converter is operating at a firing angle of $${60^ \circ }.$$

If the firing pulses are suddenly removed, the steady state voltage $$\left( {{V_0}} \right)$$ waveform of the converter will become

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

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 single phase full bridge converter supplies a load drawing constant and ripple free load current. If the triggering angle is $${30^ \circ },$$ the input power factor will be
