摘　　要：以微型燃机驱动高速电机为核心的分布式发电系统受到了广泛的关注。由于高速电机输出的高频交流电能不能被直接应用,需要采用适当的电力变换系统。提出了一种用于分布式发电系统的双向变流器拓扑结构和基于空间电压矢量脉宽调制(SVPWM)的控制原理及实现步骤。此变流器在机组起动时,被用作逆变器;机组正常发电时,用作整流器,将交流电转换为直流电。仿真结果表明:所设计的结构和采用的控制策略是可行的。More attention has been paid to distributed power system of high speed generator driven by micro-turbine. Since high-frequency electrical power of high-speed generator output can not be directly used, power converter system requires to be adopted. The structure and SVPWM control strategy of a specially designed hi-directional power converter for the distributed power generation system of high speed generator driven by micro-turbine were introduced. The converter was used as an inverter to drive the generator for the micro-turbine starting, and as a PWM rectifier to convert the high frequency output AC power into DC power during the normal operation of the generator. The simulation result shows the feasibility of the proposed design structure and control strategy.
