This paper presents the novel method not only to suppress the input current harmonics but also to realize the low frequency output voltage ripple using the multiple-input ac-dc converter, which is considered from viewpoints of the relatively small power application and simple circuit configuration. The operation principle and control strategy of the proposed circuit are discussed. As a result, it is clarified that the new circuit has excellent performance characteristics such as high power factor over 0.99, low total harmonic current distortion factor less than 9.2% and low output voltage ripple of 40 mV.
