Current
An Artificial Invasion

Jason Lomberg, North American Editor, PSD

­The world is buzzing over the capabilities, potential, and in some cases, legal implications, of artificial intelligence, and for good reason. In a very real sense, this feels like the hype that preceded the very first personal computers, before they became an inseparable part of the human experience. Like late ‘80s/early

­Even while accounting for DC power distribution, the disparity between input and output voltages gets larger, with supply rails often subject to wide variations, while the outputs, sometimes down to around 1V, must be ever-more accurate and disturbance-free. Power conversion in a single stage with isolation

Figure 1. Simplified buck converter power stage

­Every SMPS works by storing energy in an inductor and utilizing pulse width modulation (PWM) techniques to obtain the desired output. The guiding principle of these converters is the volt second balance law, which dictates that when operating in a steady state, over one period the average current of an inductor mu
