Zusammenfassung:	A boost circuit and method is described for supplying a boost voltage to a rotor of the electric machine, just as the electric machine is pulsed on, the boost voltage aids the rotor in quickly overcoming its start-up inductance, rapidly turn on the rotor. As a result, much faster transition times are realized each time the electric machine transitions from the off state to the on state at the start of a pulse. By reducing the transition time, the overall efficiency of the electric machine is significantly improved.
