It converts incoming AC power to DC (rectification) and then converts that DC to high-frequency AC (inversion) to create the precise, controllable power needed for efficient welding operations.
IGBTs (Insulated Gate Bipolar Transistors) and MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are semiconductor switches that handle high currents and frequencies efficiently, enabling compact, reliable power conversion with minimal heat loss in welding applications.
The high-frequency transformer steps down the voltage while increasing current, allowing for smaller, lighter components and better arc stability, resulting in more precise control, improved energy efficiency, and higher quality welds.
