Flying high in dream

Fly fly fly . . . High. . . Charming
Fly fly fly . . . Back. . . Nostalgic
Flyback . . . Boring
Flyback converter. . . Measuring my patience
Flyback when went to forward,
Fully controlled converted to semicrack. . .
The rising currents dont know where to go. . .
But we the participants know , its tea-time
The zig-zag waveforms looks like samosa
And the rising voltages, Steaming tea. . .
Lucky who slept, and funny in the scene. . .
Postures are different, but all are on the same course. . .
And at the end, everyone will be blessed with certificate of excellence,
For not disturbing the tutor with questions. . .
