Excellent. So, I can understand why one might use a flyback, when the supply source is already DC (portable battery device) and the circuit requires AC. What are the circumstances where an AC supply is rectified to DC and a flyback is used to change it back to AC, as in your example? What are the advantages of doing so? Please and thank you.

The name comes from cathode ray tube television deflection output transformer.. Horizontal deflection work similarly; switch turns on in sync with video and current starts to rise in deflection magnetics; after linearish horizontal sweep energy is stored in deflection magnetics. Then switch opens and deflection circuit oscillates through flyback diode with flyback capacitor to get the crt electron beam 'FLY' back to zero very fast. The energy of collapsing magnetic field is transferred to eg. deflection output transformer high voltage coil among other coils..then the cycle starts over to draw the next line alla the time initiated by video sync circuit.. The name is inherited there!
