A single-phase full bridge voltage source inverter $\text{(VSI)}$ feeds a purely inductive load. The inverter output voltage is a square wave in $180^{\circ}$ conduction mode. The fundamental frequency of the output voltage is $50 \mathrm{~Hz}$. If the $\text{DC}$ input voltage of the inverter is $100 \mathrm{~V}$ and the value of the load inductance is $20 \mathrm{mH}$, the peak-topeak load current in amperes is _____________ (rounded off to the nearest integer).
