The Converter component is used to model rectifiers (AC/DC converter) with ElectricalOM, and it has two versions, 3Ph and 1Ph. A rectifier cannot be inserted after a Source and it needs a distribution node to get connected. Converter component supports Multiple Sources feature, and it can also be used to model multiple rectifiers running in parallel, see Multiple Converter Scheme.




Circuit edit tab of a Converter has a Rectifier settings section instead of a Load section, where the user can define various parameters related with the rectifier.



Left hand side of the rectifier symbol indicates the AC side parameters:

L-N Voltage and L-N Voltage (In case of a 3Ph version): These indicate the line to neutral and line to line voltage on the AC side of the rectifier and it is picked up by ElectrcialOM automatically depending on the feeder circuit.

Right hand side of the symbol represents the DC side parameters:

L-N Voltage: This parameter is defined by the user manually by typing in a value.

Other parameters:

Voltage drop (%): This field denotes the voltage drop permissible after the transformer in percent. The global voltage drop limit (see Source properties Tab section) will be applicable up to the incomer side of the rectifier, where rectifier's voltage drop setting will be applicable to any downstream circuits.

kW/Rect: This is set by the user and it indicated the power of a rectifier. This parameter is for an individual rectifier and in the case of multiple rectifiers it will be multiplied by the number of rectifiers.

No. of Rectifiers Link: The user may set multiple rectifiers as parallel using this link, See, Multiple Converter Scheme for details.

Ipf(kA): Prospective fault current parameter is defined by the user by typing in the required value.

Only single phase components are available for the DC side of the rectifier. When a 1Ph component is inserted to the DC side, then it will be marked as a DC circuit.



ElectricalOM will consider a DC circuit as an ELV as long as the DC side voltage is not above 120V and there will be no earth connection consideration (a two core cable will be selected) unless the user specifically selects Use CPC tick box. If this options is enabled then the Earthing tab will also be enabled.



If the voltage is above 120V, then ElectrcialOM will asthmatically consider an earth conductor and will include related calculation and checks.
