Welding inverters usually use 380V AC input. Generally, the power is in the tens of kW. The PFC boost + half-bridge topology is used. On the high-voltage side, the current is about several hundreds amperes. Therefore, generally, 1200V or 1700V high-current IGBTs in EconoDual™3 and PrimePack packages are used.
