The figure shows two buck converters connected in parallel. The common input dc voltage
for the converters has a value of 100 V. The converters have inductors of identical value.
The load resistance is 1 $$\Omega $$. The capacitor voltage has negligible ripple. Both converters
operate in the continuous conduction mode. The switching frequency is 1 kHz, 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 $${i_{S1}}$$, the current of switch S1 (in
Ampere), is _____ (up to 2 decimal places).

A dc to dc converter shown in the figure is charging a battery bank, B2 whose voltage is
constant at 150 V. B1 is another battery bank whose voltage is constant at 50 V. The value
of the inductor, L is 5 mH and the ideal switch, S is operated with a switching frequency of
5 kHz with a duty ratio of 0.4. Once the circuit has attained steady state and assuming the
diode D to be ideal, the power transferred from B1 to B2 (in Watt) is ___________ (up to 2
decimal places).

In the circuit shown all elements are ideal and the switch $$S$$ is operated at $$10$$ $$kHz$$ and $$60$$% duty ratio. The capacitor is large enough so that the ripple across it is negligible and at steady state acquires a voltage as shown. The peak current in amperes drawn from the $$50$$ $$V$$ $$DC$$ source is ________. (Give the answer up to one decimal place.)
