摘　　要：目前,国内外变频功率标准源的输出电压电流范围普遍局限于1 000V/80A以内,且最低频率为10Hz左右,无法满足实际变频电量测量仪器计量检定的需要。大量程宽范围变频功率标准源的研制,可以完善变频电量量值溯源体系,从根本上改变了变频电量测量仪器无法溯源,检定校准无标准可依的局面。Currently, the general limitation of the output voltage and input current at home and a-broad is 1 000V/80A, with the lowest frequency of 10Hz, which can not meet the actual needs of fre-quency electricity measuring instruments to examine. The research of the standard source of variable fre-quency power of wide range, could improve the system of traceability of frequency electricity, as well as change the predicament that frequency electricity measuring instruments is unable to trace and no stand-ards can be referred to.
