CPC: in a self-oscillating arrangement (H02M7/538 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Conversion of AC power input into DC power output; Conversion of DC power input into AC power output > Conversion of DC power input into AC power output without possibility of reversal > by static converters > using discharge tubes with control electrode or semiconductor devices with control electrode > using devices of a triode or transistor type requiring continuous application of a control signal > using semiconductor devices only, e.g. single switched pulse inverters > in a self-oscillating arrangement

CPC:
