摘　　要：简要介绍了涡轮发电机工作原理及输出特性,根据其输出特性设计了发电机与负载间的电能变换器。对比各种基本拓扑结构特点选择了Buck电路作为变换器主拓扑,并采用两通道交错并联技术,分析了两通道交错并联Buck变换器工作过程。在制作的实验样机上进行实验,证明了设计的电能变换器在输入电压和负载变化的情况下可实现恒压输出,而且采用交错并联技术可减小输出电流纹波和增大纹波频率,降低对滤波电容和磁性元件的要求,提高变换器功率密度。Turbine generator working principles and output characteristics are briefly introduced, the energy converter between the generator and the load according to its output characteristics is designed.Comparing all kinds of basic topology,Buck converter as the primary topology and two-channel interleaving parallel technique are chosen,the working process of the two-channel interleaving parallel Buck converter is analyzed.The experiment confirms that the designed power converter can achieve a constant voltage output in case of input voltage and load changing, the inter- leaving parallel technique can reduce the output current ripple and increase ripple frequency, and reduce the require- ments for filter capacitor and magnetic components, and improve the converter power density.
