[edit] Is there a mistake here?

In the description of CCM mode operation it is stated that:
"It can then be concluded, that while S1 is off, power is delivered to the load from L2 and L1. C1, however is being charged by L1 during this off cycle, and will in turn recharge L1 during the on cycle."

Doesn't C1 recharge L2 instead of L1 during the on cycle?--Zama Zalotta 09:45, 27 November 2006 (UTC)

Yes, it does. This has been corrected. Thank you! CyrilB 12:23, 27 November 2006 (UTC)

There was an assertion in the text that the average current in both L1 and L2 is the same, which is not true, even in the case of coupled windings. The ripple current will be the same for both inductors (assuming the inductances are equal), and the ripple current is shared evenly between L1 and L2 in the case of coupled inductors. Please correct me if I'm mistaken!

What would happen if Cs was removed from the circuit and replaced with a dead short?

If the series capacitor Cs is replaced with a short, then L1 and L2 form a DC short circuit and the supply will not function. 70.112.175.142 16:36, 11 August 2007 (UTC) Dwight

The polarization of C1 in figure 1 is incorrect. The terminal of C1 connected to L1 is more positive than the terminal of C1 connected to L2. —Preceding unsigned comment added by 58.174.32.2 (talk) 06:44, August 24, 2007 (UTC)
