I would have thought, if the load was resistive, you would just see the
A.C. waveform, as the self-capacitance of the diode swamped out all the
other effects.  If you have a smoothing capacitor following the diode,
that would effectively be in series with the diode's self capacitance
and the two of them would act as a capacitive divider which
progressively shorted out the power supply as the frequency increased.
