According to the principle of multi-winding flux coupling , this paper presents a steady-state model of power-saver based on the zig-zag type auto-transformer .The characteristic of the power-saver equivalent circuit is studied in detail .The analysis shows the power-saver can filter out zero-sequence first harmonic and harmonic load currents , and reduce the zero-sequence current caused by the zero-sequence component of power source . The simulation results testify the aforementioned theoretical analysis .
