1. A braking system, comprising:
- a converter;
a capacitor coupled to an output of the converter;
a bridge coupled in parallel to the capacitor;
at least one inductor coupled to the bridge;
an electrically conductive disc disposed proximate to the at least one inductor; and
a switching unit controller for commanding the converter to convert a level of voltage supplied therefrom from a first voltage level to a second voltage level and thereby increase energy stored in the capacitor, and, upon receiving a brake command, commanding the bridge to ramp-up electrical current in the at least one inductor so as to induce an electromagnetic force on the electrically conductive disc.
