Powering the Smart Revolution at 277 Vac

Although we most often call them “power supplies” we normally are actually referring to “voltage supplies”. The difference between the two designs is an ideal ‘power supply’ will deliver constant power to a load regardless of the load voltage or load current . An ideal voltage supply will provide a constant voltage to a load regardless of the load current We will not be able to design, build or buy an ideal voltage supply because an ideal voltage supply will have the ability to deliver unlimited current (and power) to a load. Even though we mentioned we are discussing voltage supplies rather than power supplies, we will continue to generically use (misuse) the term ‘power supply’ in our discussions.
