摘要
提出了一种基于背靠背变换器的混合变压器拓扑。分析了拓扑具体连接方式,通过简化的原理图说明了设备的工作原理;分别对背靠背变换器的前后级工作模式及补偿模式进行阐述。详细介绍了前后级变换器的检测和控制方法。提出了一种基于全通滤波器的单相电压跌落检测方法。在此基础上通过仿真与试验验证了拓扑及所提出检测和控制方法的正确性。所提出的混合变压器同时兼具功率传输和电能质量治理的功能。
A new topology of hybrid transformer was given. Its connection methods between transformer and electronic device were analyzed in detail. Simplified circuit diagram shows the working principle of the equipment.The operation and compensation mode of pre-converter and backward-converter were described respectively. The detection and control methods of pre-converter and backward-converter were detailed discussed. A novel single phase voltage detection method based on all pass filter was presented. Based on those discussed in the paper,simulation results were provided which verifiy the correctness of the method proposed,and its function of control of power quality.
