Abstract

In this paper, an efficient power electronic circuit simulation approach is discussed for a digitally controlled three phase active PFC converter system. The control circuit simulation software used in this simulation technique is also applied to the digital signal processor (DSP) based control implementation of a practical power factor correction (PFC) power conversion circuit with a digital control scheme. This circuit simulation technique is based on a circuit equation modeled by substituting control input dependent time-varying resistors in place of all the power switches incorporated in the bridge arms of the three phase active PFC converter circuit and system treated here, one state-vector equation described by state-variables for inductors and capacitors, together with an algebraic computation method to transform the matrix of the circuit equation into matrix of the state vector equation. In addition, this paper proves the effectiveness of a voltage-fed three phase PFC converter with a digital control PWM strategy and its performance evaluations on the basis of computer-aided simulation results together with experimental results.
