Alstom medium voltage drives technical data: Alspa VDM5000 Topology 2-level Voltage Source Inverter Input section Diode/SCR 6-, 12-, 18- pulse rectifier; HV IGBT with Active Energy Management Input voltage 2300-4160V Efficiency no data Input power quality 6-pulse rectifier doesn’t meet IEEE 519 requirements, 12-pulse IEEE 519 compliance – In/Isc ratio dependent, 18-pulse and AFE meets [...]
Rockwell Automation manufactures three medium voltage drive types – all of them are CSI topology. The main differences between types are: power range, input section configuration, cabinets design – footprint, cooling and control voltage. PowerFlex 7000A ‘A’ Frame Topology Current Source Inverter Input section PWM SGCT based rectifier with input capacitors, 6-pulse SCR rectifier, 6 [...]
