Simple buck converter simscape model download

Inductor current, output voltage and switching pulse of dc to dc buck converter is shown below in figure 3,. Every dc to dc converter works in two modes of operation, one is CCM continuous conduction mode , in this mode inductor current never goes to zero and second one is DCM discontinuous conduction mode , in this mode inductor current goes to zero at every switching pulse.

Here we can see that in figure 3 this dc to dc buck converter works in CCM mode because inductor current never goes to zero. When switching pulse is positive then inductor is charged at its peak value during this, the output capacitor continuously provides the voltage to output load.

Similarly, when switch pulse is negative then this inductor is discharged through diode and charge the capacitor. This process is continued at every switch pulse of dc to dc buck converter.
