#218 In this video I take a look at the key differences between the main ways of modulating the drive signal of a switched mode power supply – Pulse width and Pulse frequency modulation. Both types of modulation end up doing the same thing – regulating the output voltage of the supply, but they each have their specific advantages and drawbacks.
More on Power supplies:
PSU Static Output: youtu.be/ESz64YnDEIg
PSU Dynamic Output: youtu.be/l0bELIic8PE
PSU Output Noise: youtu.be/vzhEt3t5VXw
PSU Loop response: youtu.be/clUtlYPEwfc
CCM/DCM: youtu.be/x_cvzHor8to
PWM/PFM: youtu.be/WYrqjXisnxA

#188 In this video I try something a bit more different than normal. Rather than talk about a specific technical subject, I want to take you trough my quest of building a power supply for home use. Its nothing particularly special, but it does not have to be, it just needs to work and be reliable.
