7.4.2.25.1 Semantic definition

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

7.4.2.25.2 Type values

Type	Description
`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.
`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.
`USERDEFINED`	User-defined type.
`NOTDEFINED`	Undefined type.
