Solid State Relays generate thermal energy during their on state conduction at approximately the rate of 1.0 to 1.5 watts per ampere of load current depending upon their design.
For reliable operation of the Solid State Relay, this energy must be dissipated into the surrounding air in order to maintain a safe operating...

A novel approach for providing microprocessor power directly from 48V is proposed. This solution enables high voltage, low current to be distributed throughout a system, minimizing distribution losses, while providing low voltage, high current direct from the 48V input in the most efficient manner possible.
This solution...

Modern power distribution systems often contain multiple power sources integrated within one system. A simple variant may be the common double-ended substation, which can be further complicated by additional emergency or alternate sources. This presents significant complexity to the designer attempting to design a protection...
