Dc-dc step down buck convertor

Hi

What effect does the inductance value have on the ripple in the output voltage?

 

[zoki85]

Higher the inductance, smaller the ripple

 

[Kasim]

Thanks

Can you explain what the reason is for this?

 

[zoki85]

In continuous mode ΔI_out=(V_in-V_out)⋅T_on/L
Waveforms for continuous mode:

Generally speaking, inductivity is inert to change of current flowing through it.

Thanks, but what do you mean by inert?

Thanks, but what do you mean by inert?

V=-L⋅di/dt

Thanks alot
