摘　　要：在工业电阻炉中,采用交流调功电路可以提高温度控制精度和产品质量,但会产生谐波。本文推导了单相交流调功电路的谐波统一公式,提出了抑制谐波的方法,其中改变加热元件结构的方法,适用于温度控制精度高和功率大范围变化的场合,而且谐波最大值可预先控制。AC power regulator circuits are applied to industrial wire-wound furnace. This circuit can improve temperature control precision and the quality of products, but the harmonic is induced. In this paper, the general harmonic equation of single phase AC power regulator circuit is deduced, and the harmonic control schemes are put forward. The heat element structure variation plan is suitable for the situation that the temperature control precision is high and the power change range is large, and the harmonic maximum can be beforehand control led.
