The first is the dynamic loss due to the energy used to charge and discharge the MOSFET gate capacitance, and is highest when the transistor (s) operate at high frequency. These switching losses occur when current flows through the drain-source channel while there is significant differential voltage across it.

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).. In addition to melting the base metal, a filler material is typically added to the ...
