| Abstract |
This paper presents the PWM voltage converter connected to the AC mains. Detailed and global models for the simulation of the system are presented. A personal computer program is introduced, allowing detailed and global simulation with system or with Park's coordinates. The numerical integration method used is an explicit Euler-Backward method. The trapezoidal integration method is also provided. Several applications for the system are possible namely in electrical drives, operating as an AC/DC converter. The DC side has characteristics of constant DC voltage source. Bidirectional power transfer capability is possible by reversing the DC current. Reactive power regulation can be done. The system can also be used as a reactive power compensator. With the evolution on the power semiconductor switches with gate turn off capability, applications on HVDC energy transmission may be feasible. Theoretical results obtained with the detailed and global models and experimental results are presented and compared. |
