电阻焊设备的电源对所有点焊机的性能起着非常重要的作用。 中频电阻焊机逆变电源输入为380V三相交流电源，经整流电路、滤波电容转变为直流电源，再经过功率开关器件组成的逆变电路转变为中频方波电源，再经变压器降压、大功率二极管整流为直流电源，作为中频电阻焊机的电极对工件进行焊接。
中频电阻焊机逆变电源控制电路由DSP和CPLD组成。 DSP产生的PWM波、检测信号、保护信号在CPLD中进行逻辑计算。 中频电阻焊机的调压电源逆变一般采用电流反馈来实现。 PWM获得相对稳定的恒流输出，中频电阻焊机逆变电源的电路供电电源电压。
U一次为逆变器输出中频电压，变压器二次电流为I二次。 调整PWM的脉冲宽度可以控制I次级的大小。 逆变电流采用全桥结构。 其主要特点是主变压器工作能力强。 主电路由4个IGBT和一个中频变压器组成。 将直流电压转换成中频方波交流电压，送入中频变压器。 经过解压、整流、滤波后输出。 电路的稳定性来源于IGBT的稳定工作。
