Re: Power Supply Transformers

RayHex,


The power supply transformer delivers its entire output to rectifiers
and capacitors which is neither a reactive or capactive load. The
resultant output is pure DC, where the voltage is always in phase with
the current. Therefore its impossible to impedance match the power
supply transformer to the DC load.
