PWM control is promising to achieve a unity power factor and to improve the input current distortion in a high performance current-source three-phase AC/DC converter system. In contrast to the voltage-source converter, the LC filter connected between the source and the converter may cause an LC resonance both in steady and transient states. Many reports have been published to improve the current distortion in steady state and to suppress the current oscillation in transient state of the current-source PWM converter by using the feedback control.This paper gives an analysis of the transient oscillation of the filter voltage and current, and proposes a simple open-loop suppression method by using the rate limiter of the input current reference. Furthermore, the design rule of the LC filter for the suppression control of the transient oscillation is described. The effectiveness of the proposed approach has been verified by experiments.

The authors already proposed the new control scheme of the PWM converters where the control scheme was performed on the estimated voltage and phase of the source, thus eliminating the voltage sensor.The paper deals with a stability problem of a sensorless PWM converter control. Under consideration of the parameter error, the stability analysis of the proposed control is examined. In addition to that, a design procedure of the estimation gains is also examined. For the stable starting of the system, the initial estimation of the amplitude and phase angle of the source voltage is proposed.The effectiveness of the theoretical stability and estimation gain design has been confirmed by experiments.
