Modular power supply system

摘要

A power distribution system intended for use in a highly modular desk top computer system is disclosed. The invention provides a programmable modular DC power supply including a power module that produces a first fixed regulated DC voltage which is coupled from the power module to a power bus. Thereafter the first voltage is distributed to a plurality of DC-to-DC convertors, each of which is operable to change the first DC voltage to a second regulated DC voltage selected from a plurality of programmed voltage values.
