摘　　要：对中频感应炉的加热原理以及其功率因数的影响因数进行了探讨,并将不能恒功率输出的并联逆变电路改进为混联逆变电路。实践表明,改进后的逆变电路能提高中频感应炉的功率因数,并能保持恒功率输出,且节能效果显著。Abstrct: Heating principle of intermediate frequency induction furnace and some factors affecting its power factor are discussed, Some betterments that parallel connection spacer circuit is replaced by interfusion connection spacer circuit are put in practice. The results reveal that full power can be output and saving energy result is remarkable.
