| Abstract: | The general theories and approaches of reactive and active power factor correction are analyzed. Then the paper introduces a new method that gives a typical shunt single-phase rectifier to correct power factor, which is controlled by PI of constant-frequency. As a result, it reduces the content of harmonic current and improves the power factor with a group of nonlinear loads. |
