Rectifier & SCR Assemblies
Overview
Powerex is your source for diode and SCR rectifier assemblies in a wide range of
configurations and ratings (up to 6500V, 4000A).
Applications
Motor controls – Low Voltage and Medium Voltage converters
SCR power bridges for solid state starters
SCR and diode based input rectifiers
Crowbar systems for motor drives
Wind power (alternative energy) – Converters available as diodes, SCRs or IGBTs
Transportation – Traction rectifiers and auxiliary rectifiers
Inductive heating – Input rectifiers
Welding systems – Input rectifiers and fast recovery diodes
Uninterruptible power supplies – SCR transfer switches and input rectifiers
Electroplating systems – Input SCRs and output rectifiers
Aviation – Standby power distribution, resistive heating
Mining – SCR power bridges, solid state starters and input rectifiers
Power distribution – SCR based transformer tap changers
Military, hybrid vehicles and power supplies
Solid state SCR based switches
Powerex complements its rectifier products with IGBT assemblies for inverters,
converters, choppers, and full or half wave bridge units. These assemblies can
also be combined to provide a system-wide solution.
