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 [...]
