| Abstract: | The harmonic characteristic of input current in single-phase voltage source PWM converter is analyzed theoretically, The relationship among input current harmonic distribution and power factor, total harmonic distortion, psophometric interference current, are discussed. The harmonic characteristic of multi-converters is analyzed, and it is proved that multi-converters is an effective way to improve the input current harmonic characteristic of PWM converter. |
