DIFF Subgroup
H02M 5/443 using devices of a thyratron or thyristor type requiring extinguishing means
Introduced: July 1974
Full Title
Conversion of AC power input into AC power output, e.g. for change of voltage, for change of frequency, for change of number of phases > with intermediate conversion into DC > by static converters > using discharge tubes or semiconductor devices to convert the intermediate DC into AC > using devices of a thyratron or thyristor type requiring extinguishing means
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
IPC defines codes here since 1974.
