Research On The Three-Phase High Powre Factor Voltage PWM Rectifier

With the serious problem of harmonics pollution to the power system ,as well as the need of high performance of AC drive application ,three- phase PWM rectifiers have been as active research topic in power electronics recently ,due to the virtues , such as sinusoidal input currents , unity power factor ,steady output voltage, good dynamics and bin-directional energy flow.First,this Paper analyzes the principle of the BOOST type PWM reversible rectifier in detail, explores space vector method to investigate its inversion ,and establishes the mathematics model in ABC coordinate, coordinate, and d q coordinate respectively.Secondly, this paper analyzes the control of hysteretic current method , explores the defect of hysteretic current control. The theory analyzes is verified by simuliation results.Then, the control of voltage space vector method is explored based on instantaneous reactive power and AC motor drive theory. The simulation is done with simulink in MATLAB and the results verified the correction of controlling solutionFinally, theoretical research on the parameters of the circuit is accomplished. In the end, this paper is put up to compare the space vector control and the hysteretic current control, clarifies the meaning of this paper.
