H02M 5/14

for conversion between circuits of different phase number

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 transformers > for conversion between circuits of different phase number

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 transformers > for conversion between circuits of different phase number

No child classifications to compare. This is a leaf node in both IPC and CPC.
