Medium Voltage SCR & Rectifier Assemblies Overview Powerex is your source for Medium Voltage SCR and rectifier assemblies in a wide range of ratings and configurations. HV SCR Power Stack 5MW, 24kV SCR based power section Designed for low partial discharge (low corona) Scalable to other voltage and current ratings Air cooled, modular design Applications Motor controls – Medium Voltage converters SCR power bridges for solid state starters SCR based input rectifiers Crowbar systems for motor drives Wind power (alternative energy) – Converters available as diodes or SCRs Static var compensation Resistance heating Inductive heating – Input rectifiers Load commutated inverter power section for retrofits Fiber Optic Fan Out Board Uninterruptible power supplies – SCR transfer switches and input rectifiers Receives SCR gate commands from external controller Fans out command to multiple level of SCRs Receives and processes feedback from gate boards Mining – SCR power bridges, solid state starters and input rectifiers Gate Power Supply Current loop supplies power to all the SCR levels Provides excellent voltage isolation between SCRs and controls and also provides high BIL capability Power distribution – SCR based switches Thyristor controlled reactors 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. HV Fiber Optic SCR Gate Drive Board Receives and conditions power from an isolated loop power supply current transformer, allowing for high voltage isolation Provides fiber optic triggering of gates Provides fiber optic status feedback for temperature and power supply health monitoring ® www.pwrx.com Serving Our Customers Through Expertise, Innovation and Reliability How to Select the Proper Assembly for Your Needs Areas to consider when selecting the proper assembly.
