ABSTRACT:
A system and method for switching from one voltage to another voltage are disclosed. The system relates to an induction generator or motor that switches between a first voltage and a second voltage. The method comprises transitioning between two or more voltage levels by inserting and removing resistance and capacitance following a systematic timing scheme. The generator/motor may have one or more windings, such as a primary and auxiliary winding.
