Semantic definitions at the type

Type definition

The IfcTransformerTypeEnum defines the range of different types of transformer that can be specified.

HISTORY New type in IFC2x2.

Enumeration definition

Constant	Description
CURRENT	A transformer that changes the current between circuits.
FREQUENCY	A transformer that changes the frequency between circuits.
INVERTER	A transformer that converts from direct current (DC) to alternating current (AC).
RECTIFIER	A transformer that converts from alternating current (AC) to direct current (DC).
VOLTAGE	A transformer that changes the voltage between circuits.
CHOPPER	A chopper is an electronic power DC convertor without an intermediate AC link giving a variable output voltage by varying the periods of conduction and non-conduction in an adjustable ratio.
COMBINED	A transformer that changes different quantities between circuits.
USERDEFINED	User-defined type.
NOTDEFINED	Undefined type.
