How to Wire the 'PFM OSCap' Whilst not intended as a physical layout it does show the necessary information required to wire the PSU optimally, keeping loop areas to a minimum, and proper wiring of the 0V returns. When wiring a power supply it is fundamental to understand that current flows in loops, the primary ones in the above supply are: -
It is therefore very important, in order to minimise inductance and loop areas (and thereby optimise performance and minimise both EMC radiation and pick-up problems) to keep these feed and return pairs closely coupled. Twisting pairs of wires is easiest for the beginner, but with care a wiring loom can be constructed that achieves the same effect - it just needs good wiring skills. So get practising, take your time and I promise you the results will be VERY special. More later, as it comes off the press.
