Using three-phase full-wave rectification + IGBT inverter power regulation technology, the ripple factor is less than 0.55, and the high-frequency transformer is used to replace the step-down transformer to reduce copper loss and tape loss, and the inverter efficiency is high.
Low ripple coefficient to meet the constant power output, which can be used for welding high-end automotive tubes, aluminum headers, copper tubes, and various series of stainless steel tubes
①Low voltage and high current working mode
②Two-stage LC filter, the output current is more stable.
③MOSFET is used as the inverter element.
Diode all wave rectifying add IGBT chopping to replace SCR rectifying, to improving the power factor.Save 15%~25% of electric power.
The inverter part consists of MOSFET single-phase invert bridges connected in Parallel.
