共振式直线电机及其变流器的总体功率因数研究
The Research on Total Power Factor of a Linear Oscillomotor and Its Converter
【摘要】 提出了三相桥式变流器的视在功率传输比 (APTE)的概念 ,在输出电流为三角波的条件下对该传输比作了分析计算。结合共振式直线电机功率因数的分析 ,计算出了系统总的功率因数。实验结果与理论计算吻合
【Abstract】 An idea of the apparent power transfer efficiency(APTE)for a three phase bridge converter is prensented here. The calculation of APTE for the phase controlled converter with a triangular output current waveform is deduced.On the basis of the linear oscillomotor power factor and the APTE for the converter,the total power factor is obtained.The theoretical analysis is consistent with the experimental result.
