| Abstract: |
| As the interface between PMSG(Permanent Magnet Synchronous Generator) and grid,thenormal converter configurations of direct - drive wind power system with PMSG are analyzed, including the diode rectifier inverter,the diode rectifier DC/DC converter inverter,and the back - to - back dual PWM converter. Their working principles,implementations,advantages and disadvantages are discussed and compared. The topological characteristics and applications of some high power converters are introduced in detail. The diode rectifier Boost converter inverter and the back - to - back dual PWM converter are currently the optimal solutions,and the multilevel converter has a promising prospect for its excellent performance. |
