摘　　要：软开关逆变电源是各类焊接电源的主要研究方向,详细介绍了所研制的全桥式零电压开通逆变电阻焊机。该主电路以工业用控制计算机为控制核心,选用IGBT为功率开关元件,以改进后的EXB841驱动电路进行驱动。研究结果表明,该系统工作稳定可靠,具有良好的过流保护功能,通过优化电路参数和适当地设置软件参数,可以在不需增加任何附加电感的情况下,实现了IGBT功率开关元件的零电压通断。Study of various soft-switching welding power is a main developing direction in the world recent years. A novel zero-voltage-switching (ZVS) full-bridge (FB) pulse-width modulated (PWM) inverter resistance welding power source is introduced. The inverter resistance welding power source is controlled by an industrial processing computer (IPC), and insulated gate bipolar transistors (IGBT), driven by improved EXB841, are used as the power switches in the inverter circuit. The research conclusion shows that the inverter resistance welding power source can work reliably and stably, and has sensible protection function for overcurrent in the circuit, and by optimizing circuit parameters and programming software properly, power switches can be operated with zero-voltage-switching (ZVS).
