Decades of experience drives one-of-a-kind switched-mode power supply training

Power supplies are probably not something you spend a lot of time thinking about when you purchase a new laptop or TV. Most people just plug them into the power source and never think about them again. In reality, though, power supplies are a crucial part of fueling just about every piece of electronic equipment you own. They do this by taking the full power of the alternating current (AC) input from the grid, known as mains, and converting it into the usable voltage that gives life to electronics.

“Essentially every piece of electronic equipment, with the exception of a very few, needs an AC adaptor, externally or internally, to make use of the energy from the mains,” explains Frans Pansier, former Philips and NXP power supply specialist and High Tech Institute instructor with more than decades of experience in the domain. “Otherwise, the full flow of the 230 volts from the mains would fry the electronics and cause a lot of safety issues.”
