with automatic control of output voltage or current, e.g. switching regulators

Full Title

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 (H02M3/07 takes precedence) > using devices of a thyratron or thyristor type requiring extinguishing means > using semiconductor devices only > with automatic control of output voltage or current, e.g. switching regulators
