The role of the static switch in supplying continuous power under all conditions

Uninterruptible Power Supplies (UPS) support critical loads by using stored energy during mains power blackouts. But they must also offer protection from electrical noise, spikes and surges as well as overloads and possibly even failures within themselves.

In a recently published article, Alan Luscombe, Director at Uninterruptible Power Supplies Ltd., a Kohler company, explores the role of static switches and their contribution to UPS protection, especially with systems that have a modular topology.

His conclusion:

„Modern UPS systems are seldom single-channel architectures; modular implementations offer many advantages. However, these installations must be internally synchronised to function successfully, with all modules either on inverter or on bypass. The use of one static switch per module is favoured, to avoid a single point of failure.

Today’s UPS systems, especially those that use modular technology, are flexible and easily scalable while protecting their critical load from many different threat types. Static switches play a key role in assuring this resilient performance.“
