Stabilizing compressor operation in variable frequency air conditioners to improve reliability and reduce noise. The method involves switching between two winding modes in the compressor motor to prevent instability when accelerating to target frequencies. If the target frequency is below a dividing point, the compressor operates in one winding mode.
