Abstract
A braking system is described in which a synchronous electric machine mechanically coupleable to one or more wheels of a vehicle is used as a means of providing a controllable braking torque in the event that one or more of the components in the power train (for example the battery or inverter powering the synchronous electric machine) is in a fault condition. In such a fault condition, the electric machine generates uncontrolled regenerated currents when the rotor is rotating. A dump resistor is used to dissipate the uncontrolled regenerated currents and one or more switches in the current flow path are used to modulate the power through the dump resistor, thus creating a controllable braking system.
