Electric winding exchanger system

An electric winding exchanger system comprises:

• an electronic control unit;
• a back electromotive force (EMF) boosting circuit;
• a plurality of high-voltage terminals;
• an electric motor;
• a motor control unit;
• the electric motor comprises a plurality of winding sets;
• each of the plurality of winding sets comprises a plurality of coils and a neutral point;
• the motor control unit being electronically connected to the electronic control unit;
• the electronic control unit being electronically connected to the back EMF boosting circuit;
• the electric motor being configured to operate through a plurality of electrical phases, wherein each of the plurality of electrical phases is associated to a corresponding high-voltage terminal from the plurality of high-voltage terminals and a corresponding coil from the plurality of coils;
• the neutral point being selectively and electrically connected to each of the plurality of coils;
• the corresponding coil being selectively and electrically connected to the back EMF boosting circuit by the corresponding high-voltage terminal;
• and
• the corresponding coil for an arbitrary winding set being selectively and electrically connected to the corresponding coil for another winding set, wherein the arbitrary winding set and the other winding set are from the plurality of winding sets.
