GATE Electrical Engineering (EE) 2018 Solved Paper

The figure shows two buck converters connected in parallel. The common input dc voltage for the converters has a value of $100\mathit{V}$. The converters have inductors of identical value. The load resistance is $1\mathit{\Omega }$. The capacitor voltage has negligible ripple. Both converters operate in the continuous conduction mode. The switching frequency is $1\mathit{k}\mathit{H}\mathit{z}$, and the switch control signals are as shown. The circuit operates in the steady-state. Assuming that the converters share the load equally, the average value of ${\mathit{i}}_{\mathit{s}\mathit{t}}$, the current of switch $\mathit{S}1$ (in ampere) is ___________(upto 2 decimal places).
