Based on the new duty cycle created by the 3:1 tapped inductor, we can calculate as before the necessary minimum inductance of the freewheel part of the choke winding. Since the new extended duty ...

It is noteworthy to mention that in continuous conduction mode, the freewheel diode (Fig. 1) is hard switched at turn off by the MOSFET turning on.The channel of the MOSFET has to sweep out the ...
