by static converters (controlling transformers, reactors or choke coils, e.g. by tap changing H02P13/00)

Introduced: September 1968

Title

Titles differ between systems:

IPC: by static converters

CPC: by static converters (controlling transformers, reactors or choke coils, e.g. by tap changing H02P13/00)

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

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)

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
