High current transformer for use in high power application such as electric welding process, has semiconductor switch e.g. MOSFET is provided at downstream of secondary winding for synchronous rectification of output voltage

摘要

The high current transformer (2) has a primary winding, a secondary winding (3) and a ferromagnetic material core. A semiconductor switch (5) e.g. MOSFET is provided at downstream of secondary winding for synchronous rectification of output voltage (1) with respect to input voltage applied to primary winding.
