The paper presents a three-phase PWM AC-to-DC converter that employs an inductive energy transfer mechanism (DC reactor). This converter has a wide control range of DC voltage by means of its step-up and step-down characteristics. The source current can be sinusoidally waveshaped in phase with the source voltage by means of the proposed PWM control strategy. The power factor becomes unity in the controlled range of DC voltage. The input filter parameters are decided. Then, waveforms of voltages and currents, input, output and dynamic characteristics are discussed by the computer simulation and their validity is confirmed by experiments.
