What are two mode of conduction for Buck converters?

Mode I : Switch is ON, Diode is OFF.
The voltage across the capacitance in steady state is equal to the output voltage. The inductor current is continuous and, this is made possible by selecting an appropriate value of L.
The inductor current in steady state rises from a value with a positive slope to a maximum value during the ON state and then drops back down to the initial value witha negative slope. Therefore the net change of the inductor current over anyone complete cycle is zero.
Mode II: Switch is OFF, Diode is ON.
The energy stored in the inductor is released and is ultimately dissipated in the load resistance, and this helps to maintain the flow of current through the load.
