DIFF Subgroup
H02M 5/06 using impedances
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
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 > without intermediate conversion into DC > by static converters > using impedances
CPC:
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 > without intermediate conversion into DC > by static converters (controlling transformers, reactors or choke coils, e.g. by tap changing H02P13/00) > using impedances
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
