摘要
随着电力电子技术与相关元器件的高速发展,电力电子变压器开始大量的应用在电力系统的配电网中。电力电子变压器通过对高频电压脉冲进行控制来实现二次侧稳定输出。对电力电子变压器的典型拓扑结构进行工作原理分析,建立了数学模型,最终通过仿真对其工作性能进行了验证,仿真结果表明电力电子变压器性能良好,对比与传统变压器,在一定程度上能够降低经济成本和空间成本,提高电能质量。
With the rapid development of power electronics and related components, power electronic transformers have begun to be used in a large number of power distribution networks. The power electronic transformer realizes secondary stable output by controlling high-frequency voltage pulses. The working principle of typical topological structure of the power electronic transformer is analyzed, a mathematical model is established, and the performance of the power electronic transformer is verified through simulation. The simulation results show that the power electronic transformer has good performance. Compared with the traditional transformer, the economy cost and space cost are reduced to some extent, and power quality is improved.
