| Abstract: | Describing the advantages of SMPS(switching mode power supply) and the construction of high-power Arc power supply system,a design method of arc power supply is proposed taking the SG3525 chip as core controller.Applying a full -bridged inverter to the main circuit of the power supply system,a stable current output is provided via PWM(pulse width modulation) controlled in average current mode.With the software OrCAD15.7 used for main/control circuit modeling and closed-loop simulation,it is shown that the t... |
