This study introduces two types of selfoscillating
circuits that are frequently found in power electronics applications.
Special effort is made to relate the circuits to the analogous mechanical
systems of some important scientific inventions Galileo’s pendulum
clock and Coulomb’s friction model. A little touch of related history
and philosophy of science will hopefully encourage curiosity, advance
the understanding of selfoscillating systems and satisfy the aspiration
of some students for scientific literacy. Finally, the two selfoscillating
circuits are applied to design a simple classD audio amplifier.
