Abstract
This paper investigates operating characteristics of three-phase matrix converter with unity input power factor by direct duty-ratio pulse-width modulation in the case of balanced and unbalanced load. It can be found from the system analysis that (1) The control algorithm for unity power factor is not related to the variables of load sides but the input voltages, (2) With the balanced three-phase load except for the pure reactive load, the unity input power factor can be achieved, (3) In the case of the unbalanced linear load, the equivalent input characteristics of the matrix converter can be seen like the nonlinear resister, (4) When the input frequency and the output frequency have the specific relationship, each input phases have the same sharing of the average power. The feasibility and validity of the analysis were verified by simulation and experimental results.
