Average output current for step down chopper (Buck converter) Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Current = Duty Cycle*(Source voltage/Resistance)
Iavg = D*(Vs/R)
This formula uses 3 Variables
Variables Used
Duty Cycle- A Duty cycle or power cycle is the fraction of one period in which a signal or system is active.
Source voltage - Source voltage A voltage source is a two-terminal device that can maintain a fixed voltage. (Measured in Volt)
Resistance - Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm. (Measured in Ohm)

Explain the operating principle of Buck converter?

A buck converter has two switches, one is a solid state switch and the other switch is a freewheeling diode. The combination of these two switches forms a connection with a low-pass LC filter in order to reduce current or voltage ripples. This helps in generating regulated dc output. A pure resistor is connected across this whole arrangement that acts as a load of the circuit.

The whole operation of the circuit takes place in two modes. The first mode is the one when the power MOSFET i.e., switch S1 is closed.
In this mode of operation, switch S1 is in closed condition thus allows the flow of current to take place through it.
Now, the second mode of operation takes place when switch S2 is closed and S1 gets open. The inductor in the circuit will store the energy so, once S1 will get open the inductor in the circuit will start acting as the source.
