Harmonic Suppressible AC/DC converter |
A harmonic suppressible AC/DC converter is only adapted to detect an input current and an output DC voltage, which is proportional to the input current, to an input side of the AC/DC converter. The input side of the AC/DC converter acts as a virtual resistor with a linear resistance characteristic, thereby obtaining an input current with high power factors and low harmonic distortion. The AC/DC converter converts energy from a power source to a stabilized DC voltage to supply to a DC load.The input current with high power factors and low harmonic distortion can therefore be provided without detecting and AC volage of a power source. As voltage frequencies of the power source are changed, acting the AC/DC converter as the virtual resistor can synchronously change frequencies of the input current. Under these conditions of changes in voltage frequencies of the power source, the AC/DC converter can be normally operated to obtain the input current with high power factors and low harmonic distortion. |
