Power conversion device frame packaging apparatus and methods
A plastic frame for converting a powered printed circuit board to an open frame power supply suitable for mounting on standoffs includes a ground plane that fits beneath the power supply combined with the solid plastic cover to electrically isolate the ground plane and a second printed circuit board providing the isolated ground plane with the powered printed circuit board matching standard power supply board and mounting dimensions.
1 ) A plastic frame that converts the power printed circuit board to an open frame power supply suitable for mounting on stand-offs, comprising:
a) versions of this frame with various options to attach input and output connectors;
b) versions with solid plastic bottom to provide electrical isolation beneath the power supply;
c) a ground plane that fits beneath the power supply, combined with a solid plastic cover to electrically isolate the ground plane;
d) a second printed circuit board can also be used to provide the isolated ground plane. The frame could house the power printed circuit board and the ground plane printed circuit board and provide electrical connections between the two printed circuit boards;
e) versions that adapt the dimensions of the power printed circuit board to match standard power supply board or mounting dimensions;
f) frame versions that include provisions for an optional light emitting diode to indicate a selected parameter;
g) versions that would allow easy attachment of a Faraday cage;
h) versions of the frame that use edge card techniques to make electrical connections;
i) versions of the frame that use soldered or connector wire to make electrical connections to the Power printed circuit board;
j) versions of the frame that do not make electrical connections to the Power printed circuit board providing mechanical support;
k) versions of the frame with grooves, screw holes or other attachment methods to allow supports that enable perpendicular mounting of the power printed circuit board, by turning the power supply sideways this can help make more efficient use of the space inside of a chassis.
2 ) The frame of claim 1 further comprising:
a) corresponding desktop and wall-mounted power supply packages that use the same printed circuit board.
3 ) The frame of claim 1 further comprising:
a) versions of the frames with electrical connections designed for soldering to a larger printed circuit board, converting the power supply to a module.
4 ) The frame of claim 1 further comprising:
a) clips enabling mounting in a standard U-channel.
5 ) The frame of claim 1 wherein of the packages are applied to battery chargers, AC-AC converters and DC-DC converters.
6 ) The frame of claim 1 wherein
a) the frames will hold more then one power printed circuit board;
b) a bulk AC-DC printed circuit board used for initial power conversion and isolation;
c) a second board with DC-DC converters could be added to create distinct DC outputs;
d) a group of AC to single output DC power supplies giving several different DC outputs;
e) holding several different non-isolated DC-DC converters.
