Interruption is the power quality problem with the most perceivable effect on facilities. It generally affects the industrial sector, particularly the continuous process industry. In addition, the communication and
Redundancy - Simply connecting in parallel is not sufficientRedundant operation with power limiting according to NEC Class 2Connecting power supply units in parallel to increase the powerProtecting high efficiency switched-mode power suppliesSupportThe current load of internal components in the power supplies must also be considered. With the introduction of new high-efficiency circuit topologies, such as resonant circuits, passive rectifier diodes in output circuits are replaced by more efficient, actively controlled transistors. These are known as synchronous rectifiers. In addition to inc...See more on assets.new.siemens SlideShare
