摘要
传统的多重化变压器中,所采用的叠加变压器中铁心结构体积复杂、重量过大。因此本文基于多重叠加的基本原理,提出了一种新型的叠加变压器的铁心结构,逆变器方波电压输入后,高次谐波磁动势在叠加过程中被削弱,从而输出三相正弦波电流。对其建立数学模型并进行仿真分析,仿真结果验证了该方法的有效性。
The configuration of traditional multi-converter has disadvantages of large volume and heavy weight. Based on the multiple compound principle, this paper gives a novel configuration of transformer iron core, in which when square waveform voltage of inverter is inputted, high harmonics wave magnetic motive force will be suppressed during the period of compounding, and three-phase sine wave current is output. Mathematical model of the system has been set up and analyzed by simulation. The results show that the method is valid.
