is discharged to the load through the Φ

switch. But the remaining
capacitors (C
2
and C
3
) are not discharged, hence their voltages are intact. Next, the
Φ
21
switch is turned off and the Φ
22
switch is turned on, and C
2
is discharged to the
load while C
1
and C
3
are not. Finally, Φ
23
is on and only C
3
is being discharged to
the load. We will now look into how this interleaving confi guration helps further
reduce output ripples.
