SUMMARYWe present an active fixed-frequency input current controller and a low-sensitivity output voltage regulator for a voltage-sourced buck-boost type rectifier operating in the continuous current mode. The current controller enforces the input line current to track the desired sinusoidal waveform in phase with the input source voltage, ensuring a near-unity power-factor operation of the rectifier. The current control strategy actively shapes the input current allowing a near-sinusoidal input current even with high variations in the DC inductor current. A lowsensitivity output voltage regulator modulating the amplitude of the sinusoidal reference for the current controller is also proposed. Both the current controller and the voltage regulator are based on sliding-mode theory. Experimental results are presented and the performance compared to that obtained using a conventional Proportional Integral (PI) output voltage controller.

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.
