Abstract
A power supply to supply power to a secondary system. The power supply is adapted to receive power from a plurality of primary systems. The power supply having a first rectifier which supplies power to the secondary system from a first primary system. At least one isolated rectifier which is connected to a primary system other than the first primary system. Wherein the primary system other than the first primary system provides power to the isolated rectifier. A power supply means connected to the first rectifier and the isolated rectifier. Wherein the rectifier and the isolated rectifier provide power to the power supply and the power supply provides power to the secondary system. Wherein due to the characteristic of the isolated rectifier, it is not possible to connect the first primary system out of phase with the primary system other than the first primary system, thereby eliminating unsafe voltages.
