using discharge tubes or semiconductor devices to convert the intermediate DC into AC

Introduced: September 1968

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

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1974.
