Title: POWER CONVERTER WITH DC-BUS AND MULTIPLE PROGRAMMABLE DC OUTPUTS
Abstract:
A multi -charger and power converter system comprising a single mains input, a primary transformer for converting mains AC supply to a fixed DC supply, a plurality of DC -DC converters providing a plurality of outputs via a number of ports to meet the power requirements (voltage/current) of a very wide variety of electronic devices such as laptop computers that can be connected to the unit using cables with fixed or interchangeable connectors /tips as required to power or charge different laptops and other devices and with a power management system that enables numerous devices to be charged or powered directly through the multicharger unit from a single wall socket without tripping the ring mains or creating Health and Safety trip hazards from excessive numbers of trailing wires. The unit incorporates audio and visual safety alarms to indicate inappropriate or potentially dangerous use of ports and has a fail-safe mechanism to close down supply to prevent damage to devices and the unit if loads exceed the pre-specified upper 'safe' limits for any particular port.
