Abstract: In this paper, research and analysis of the basic principle of Single PI and over-modulation algorithm. The algorithm of field weakening control is perfect combined with high frequency over-modulation. It can improve the percentage of the DC bus, put off the field weak frequency, reduce the phase current, also improve the compressor`s COP.

Key words: Compressor, Over-modulation, Single PI
