摘　　要：针对当前金属板材在传统电加热过程中产生电火花等问题,研究了一种采用平面线圈的感应加热电源,克服了线圈对工件大小、形状等约束,尤其适合薄板金属材料的加热处理。设计了线圈结构和电源系统,感应加热电源部分采用新型ZCT-PWM Buck软斩波器调功,单相全桥逆变,串联谐振。通过实验验证了方案的可行性与合理性,改进了传统的薄钢板热处理工艺。Based on the shortcoming of the traditional electric heating produce electric spark, this paper proposes a non-contact induction heating power supply which use a new transverse flux coil. It effectively overcomes the restriction on the size of the work piece shape, especially suitable for heat treatment of metal materials. Induction heating power supply part adopts the model ZCT-PWM Buck soft chopping converter, single-phase full-bridge inverter, series resonance. The experiments verify the feasibility and rationality, which further improved the process of traditional thin metal heat treatment.
