| Abstract: | The power electronic converter is main part of the variable speed constant frequency (VSCF) supply system. A new kind of three-phase matrix converter (MC) is proposed to replace the traditional AC-DC-AC converter. The operational principle and the characteristic of the MC in the VSCF supply system are analyzed firstly. Then, the closed-loop control approach for the output voltage of a MC based on the space vector modulation (SVM) is introduced. With this approach, the output voltage of the VSCF supply system can be partly regulated by the MC itself. Therefore, the defects caused by the large time constant of the voltage regulator in the system are diminished. Experimental and simulation results demonstrate the feasibility and validity of the approach. |
