Current generators (Part 1)

Part 1 Here starts a new series of post dedicated to current generators. As usual, the idea is to describe working experimental prototypes that feature few components and quite good performances. Current generators can be found in various applications such as battery chargers (advanced ones, aka multiple stages or intelligent battery chargers), LED drivers and […]

Not so long ago, some sensors would fit in a shoe box and require 24 VDC, not to talk about the interfaces, weight, etc. These improvements are mainly due to the incorporation of advanced sensors in smart phones: camera, […]
