Abstract
A harmonic-suppressing AC/DC power converter employs a control method for permitting the AC/DC power converter only to detect an input AC current and an output DC voltage. The control method can control the AC side of the AC/DC power converter to generate a voltage which is proportional to the input AC current. Thereby, the AC/DC power converter acts as a virtual resistor having a linear resistance characteristic. Accordingly, the input AC current of the AC/DC power converter can be controlled to approximate nearly as a sinusoidal wave with the performance of high input power factor and low input harmonic current.
