System and method for distributing power between components via a magnetic coupling
First Claim
1. A data access and storage subsystem for a computer device, comprising:
- a backplane having a main power conditioning circuit that is adapted to be connected to a power supply;
a disk drive assembly having a carrier, a disk drive mounted to the carrier, and a power conditioning and distribution circuit connected to the disk drive;
a transformer having a first core portion in the backplane interconnected with the main power conditioning circuit, and a second core portion in the carrier of the disk drive assembly interconnected with the power conditioning and distribution circuit; and
wherein when the disk drive assembly is inserted into the subsystem, the first and second core portions of the transformer are magnetically coupled to each other to deliver power from the main power conditioning circuit to the power conditioning and distribution circuit for powering the disk drive.

Abstract
A redundant array of independent disk drives (RAID) is coupled to a backplane for interfacing with a computer. Each drive in the array is mounted in a carrier. The backplane has a main power circuit and each carrier has a power conditioning and distribution circuit. Each pair of power circuits interfaces via a connectorless magnetic coupling having a core transformer with two halves. Half of the split core transformer is contained within each of the backplane and the carrier. The main power circuits deliver power to the magnetically coupled split core transformer halves, which then deliver electrical power to their respective power conditioning and distribution circuits on the carriers to provide power to the drives.
