摘要:
为提高电力电子变压器(PET)的功率密度和效率,提出了一种基于能量注入式DC-DC 变换器的PET 及其控制方法,其以Buck 变换器为基础,采用对称的拓扑结构,工作在能量注入的方式下。文章详细分析了其在能量注入与自由振荡两种模式下的工作模态和工作原理。仿真结果显示,DC-DC 变换器不仅始终工作在谐振软开关状态,且在负载动态切换时也能保持恒流输出的特性,同时该PET 能够实现能量双向流动且电能利用效率得到提高。
Abstract:
In order to improve the power density and efficiency of power electronic transformer, this paper presented a power electronic transformer using DC-DC converter based on energy injection control. It is based on the Buck converter, using a symmetrical topology and working in the energy injection mode. In this paper, working modes and working principle of both energy injection and free oscillation were analyzed in detail. Simulation results were presented to demonstrate the DC-DC converter always works in resonant softswitching state and maintains constant output current under dynamic load. It also verified that this novel power electronic transformer can achieve bidirectional power transfer and improve the efficiency.
