中文摘要:
      提出一种能量单向传输的、能在高压下完成单位功率因数整流的三相线电压级联VIENNA变换器拓扑,此新型变换器可作为新一代高频隔离中高压变压变频器的整流级。分析了该拓扑的工作原理及向更高级数拓展的方法,提出了相应的控制策略,并进行了仿真研究。理论分析和仿真结果表明,所提新型变换器拓扑在合适的控制策略下,可以具有很高的功率因数和很低的总谐波畸变THD;可以始终保持各模块直流输出电压均衡一致性。与传统级联变换器相比,可大大减少全控器件个数和耐压值,从而使得控制复杂度和成本均得以降低。
英文摘要:
      The topology of a three-phase line voltage cascaded VIENNA converter, which can complete the unit power factor rectifier under high voltage and with unidirectional transmission of energy, is proposed in this paper. This novel converter can be used as a new generation of high-frequency isolation medium-and high-voltage transformer rectifier. The working principle of this topology and the method to extend the series to a higher cascaded level are analyzed. In addition, the corresponding control strategy is put forward, and simulations are carried out. Theoretical analysis and simulation results show that under a suitable control strategy, the topology of the novel converter can achieve a very high power factor and a very low total harmonic distortion(THD); besides, it can always maintain the ba-lance and consistency of DC-side output voltage from different modules. Compared with the traditional cascaded co-nverter, the number of fully controlled devices and the value of voltage resistance decrease greatly. In this way, both the complexity and cost of the control can be reduced.
