摘要
介绍了一种软开关逆变焊接电源平台,功率电路采用饱和电感式FB-ZVZCS-PWM变换器拓扑,控制系统采用有限双极性控制模式,其中以3片Atmega16单片机完成给定、显示、遥控等功能,以UC3846为核心芯片设计了ZVZCS-PW M控制电路。试验表明该焊接电源平台性能稳定,效率高,具有良好的电气性能。该焊接电源平台可作为焊条焊、TIG焊、CO2焊、埋弧焊等的研究基础。
A soft-switch inverter welding power supply is developed,FB-ZVZCS-PWM topology with saturable inductor is used in power circuit, and limited bipolar control mode is used in control system,within which 3 MCU of Atmega16 is used to set,display and telecontrol,etc,UC3846 is used as main chip to constitute ZVZCS-PMW control circuit.Research presented this welding power supply has stable performance,high efficiency,good electrical performance,and can be used as research basis for SMAW,TIG welding,CO2 welding, submerged arc welding, etc.
