Electrical Schematic Diagram
Input AC 220V/230V/240V,rectifier and filter it into 300VDC.
Control the IGBT by PWM+PFM,inverter the 300VDC to 40KHz AC.
High frequency transformer pass the power by insulation and voltage reducing with high efficiency.
Output the second rectifier and the second filter. Output the required welding current and voltage.
