Title:
SYSTEM TO PROVIDE AC OR DC POWER TO ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2021/046123
Kind Code:
A3
Abstract:
A system and method is provided to provide power to a load or electronic equipment which includes a multi-pole switch that connects the input of the load or electronic equipment to a first AC source or a DC source or an optional second AC source created from the DC source through a DC-AC converter. The connection to the DC source is either direct or through a DC-DC converter that provides voltage adjustment or isolation. A controller changes the position of the switch in response to the sensing of the presence and magnitude of the sources or in response to an external command to select a preferred source. The controller further activates or deactivates the DC-DC and DC-AC converters to improve system efficiency.
