Sketch the source current i1 and the diode current iD for the buck converter of Fig. 10-2 with continuous inductor current.
When Q is ON, i1 iL and iD 0. If Q is OFF, i1 0 and iD iL . From these observations, the current i1 and iD can be sketched based on Fig. 10-3. The results are shown in Fig. 10-10.

Determine a set of equations that describe the instantaneous inductor current iL t over a period Ts for the buck converter.
Refer to iL and vL of Fig. 10-3. For 0 t DTs , application of (10.2) gives V1 V2 t L 1

For DTs t Ts , create a t 0 -coordinate frame with origin at t DTs so that t 0 t DTs . In the t 0 frame, application of (2) from Example 10.1 yields iL t 0 Imax V2 0 V t Imax 2 t DTs L L Evaluate (1) for t DTs to nd 3 V1 V2 DTs L 2
To complete the work, expressions for Imax and Imin must be found. iL DTs Imax Imin

For work to this point, the output voltage of the buck converter has been assumed constant v2 V2 for su ciently large values of C; however, since iC is a time-varying quantity, v2 does display a small peak-to-peak ripple v2 . Use the change in capacitor charge QC , under the assumption that the time-varying component of iL ows through C, to calculate the voltage ripple v2 for the case of continuous inductor current.
