Inventor: RAMAKRISHNAN SRIRAM
IPC: H02M1/12
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To attenuate the high frequency noise by arranging capacitors alternately with the output buses of converters within the first plane, and lining up inductors with the capacitors and the output buses of the converters positioned among these inductors, within the second plane orthogonal to the first plane. SOLUTION: A power converter 12 receives power from an adjusting power source, and converts the adjusted input voltage into many output voltages small in ripple, low in noise, and precise in degree of adjustment. An output matrix filter 14 is utilized for each output of the power converter 12, and besides a local matrix filter 16 is utilized for the entry point near each load 18. For example, the power converter 13 has three outputs, and each output is coupled with its relevant output matrix filter 14, and the power is distributed to load 18 through a distribution bus 20 of low noise. Hereby, a low-noise power distribution system can be achieved.
