More Flyback currents
 

Here are some more plots showing winding current (red), capacitor current
(magenta), and output current (green).

This time, the output current of the converter is maintained at 1 amp as
the duty cycle varies.

I've also included some plots showing the current waveforms.

As before, these plots are for an idealized converter, so don't attach too
much significance to D near 0 or 1.

As part of my refresher penance, find attached a similar summary. If
there are errors, perhaps someone could point them out.

Using piece-wise linear formulas the attached drawing puts numbers on
the constant output current plot. The spreadsheet is attached for
anyone wanting to fiddle with more numbers.

Of great..... the current waveforms are backwards......but the
analysis should still hold.

Lovely.
