Power Transistors: Overlooking the Essential

Image
Processors, 2nm, RAM, memory, and especially VLSI are the buzzwords used in every news article, every LinkedIn post, every CV, and is currently ringing in everyone’s head. This is the new IT craze. Everyone is opting for courses which focus on designing these devices after seeing the amount of compensation industry giants like Nvidia, Qualcomm, AMD, Samsung, and others are providing. Yet have we thought what goes into powering these devices?  Figure 1: A power MOSFET (IRFZ44N) (left) and a Central Processing Unit (right) You must have noticed a small thing connected to every electrical appliance called a plug. It connects to a socket which is connected to the main power supply of your house. It provides 240V RMS, 50 Hz AC supply. Now what I have just written may seem like a foreign language to some of you so let us decode it. Figure 2: MATLAB plot of AC voltage Alternating current (AC) is a form of power transmission where electrons do not flow in one direction but oscillate ...
