Power Electronics for UPS Systems

The availability of infrastructure systems strongly depends on reliable supply power, irrespective of whether these systems consist of servers and cloud storage, critical traffic control or hospital services. Uninterruptable power supplies (UPS) ensure their continuous operation. In SEMIKRON power modules, flexible topologies equipped with the latest IGBT and diode chips ensure the highest of conversion efficiencies for double conversion UPS systems.

MiniSKiiP Dual Split MLI for 1000V systems

Application Example

MiniSKiiP Dual Split MLI for 1000V systems

  • Maximum power density for 19" based modular UPS systems
  • 3-phase 150kVA system in 19" width
