Abstract: A power supply arrangement (1) has a first input for connecting to a first power source, at least one second input for connecting to at least one second power source and an output for connecting to a load. The arrangement (1) comprises at least two paralleled inverter modules (11, 12, 13) supplied by said at least one second input and a static switch (30) for switching a connection from said first power source to said load. Each of said inverter modules (11, 12, 13) comprises an internal switch (11a, 12a, 13a) for switching a connection from the respective inverter module (11, 12, 13) to said load. This architecture allows for directly connecting the critical load to the inverter group (10), thereby eliminating the susceptibility for single point failures at a common static switch for all inverter modules. Redundancy of the whole system may be easily established or increased by providing additional inverter modules.

Abstract: A connector (6, 7, 18, 23) has at least one free-standing pin (8 to 11; 19 to 22; 24, 25), which can be connected to a conductor of a printed circuit board (28). For producing the connector, a profiled, prism or rod-shaped starting body (30) is, on one end thereof, machined by turning around an axis (A) such that at least one pin is formed from an edge or profiling of the starting body. The method is significantly more economical than prior art milling methods and results in the production of especially stabile pins in the case of an extruded starting body.
