When designing power distribution for a facility, you must assume a lighting load no less than that in Table 220.12 [220.12] if the table specifies your occupancy. Should you use this table for work ...

Everyone should be well aware of the fact that lighting load in a commercial or educational type building runs at about 30% to 40% of the total building load. Everyone should be well aware of the fact ...

This video provides a light load efficiency product demonstration of HiperPFS-3 family of devices. These devices have efficient light load mode of operation and a variable frequency control algorithm ...

Switch-mode power supplies (SMPS) like dc-dc converters provide their best efficiency with heavier loads. When a device using a dc-dc converter goes into standby mode, efficiency drops considerable.

Fig 1. Designers can parallel identical fixed-ratio isolated bus converters to create the high-power array in an intermediate bus architecture. Fig 2. This array of identical fixed-ratio isolated bus ...
