Abstract
An induction motor circuit which effectively prevents voltage spikes caused by leakage inductance of the induction motor stator windings without otherwise interfering with the overall operation of the induction motor. The circuit incorporates two windings between a common point and the positive supply and two other windings between the common point and the negative supply. Voltage spikes are suppressed by diodes connecting directly from the ends of each of the windings to the supply terminals oriented to the opposite end of the respective windings.
