Uninterruptible Power Supply (UPS)

The Uninterruptible Power Supply (UPS) aims at securing the availability of critical load supplies in case of failures. Both static and dynamic methods are used. Static UPS-methods secure the power supply with batteries, dynamic UPS-methods use cinetic energy in the form of mass, i.e. a rotor. Static systems are needed in case of a hold-up time exeeding two minutes. The innovative systems may conditionally equalise capacitive and inductive loads without negatively affecting the output.
