Looking at Pulse Width Modulation and Pulse Frequency Modulation

#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.
