Definition statement

This subclass covers:

Only circuits or apparatus for the conversion of ac or dc input power into ac or dc output power, or the conversion of ac or dc input power into surge output power, or arrangements for control or regulation of such circuits or apparatus.

Relationship between large subject matter areas

The individual electro-technical devices employed when converting electric power are covered by the relevant subclasses, e.g. inductors, transformers H01F, capacitors, electrolytic rectifiers H01G, mercury-vapour rectifying or other discharge tubes H01J, semiconductor devices H01L, impedance networks or resonant circuits not primarily concerned with the transfer of electric power H03H.

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

Conversion

In respect of an electric variable, e.g. voltage or current, conversion means the change of one or more of the parameters of the variable, e.g. amplitude, frequency, phase, polarity.
