Rectifier Bridges

Single-phase and 3-phase isolated rectifier bridges for low to medium power applications. Standard and special topologies featuring diodes, thyristors and IGBTs are available in various case and terminal designs. For voltages ranging from 200V to 2200V and currents ranging from 9A to 494A.

Rectifier Bridges Benefits

When performance, space and fast production are paramount, SEMIKRON rectifier bridges are the solution in many applications.

Single or 3-phase topologies featuring diodes, thyristors and IGBTs in isolated compact cases can be achieved. Whether your preference is solder-based connection, solderless connection with spring or press-fit contacts, or mechanical screw connections, fast-on connectors or busbars, SEMIKRON has the right product for you.

Rectifier Bridges Key Features

  • Recommended for forced and natural air cooling
  • Easy mounting with or without heatsink
  • Insulated case
  • High surge current
  • Fast-on or lead connectors

Rectifier Bridges Applications

Key applications include battery chargers, motor drive input rectifiers, power supplies, DC motor control, rectifiers with PFC, AC controllers and static switches for natural convection or forced cooling.
