Power Electronics for UPS Systems

Semikron power modules feature flexible topologies equipped with the latest IGBT and diode chips ensure maximum conversion efficiency for double conversion UPS systems.

The availability of infrastructure systems strongly depends on reliable power supply, irrespective of whether these systems are servers and cloud storage systems, critical traffic control or hospital services. Uninterruptible power supplies (UPS) ensure continuous operation of these critical systems.
