CPC: using discharge tubes with control electrode or semiconductor devices with control electrode (H02M3/07 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Conversion of DC power input into DC power output > without intermediate conversion into AC > by static converters > using discharge tubes with control electrode or semiconductor devices with control electrode

CPC:

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

IPC defines codes here since 1974.
