Solid state high frequency welder technology from China

摘要

PHAMITECH Int'l, China, has launched a new solid state HF welder that uses high-power MOSFET IXFN38N100Q2 38A/1000V and fast recovery diode DSEI 2x61-12B 60A/1200V from IXYS Germany to form inverting circuit in series (VFI). The modularised design enables a more compact structure, easier maintenance and high-power realisation. The equipment is safety guaranteed by bridge-divided over-current protection technology.
