Patent Images
1. A power distribution network comprising:
- a primary charging circuit;
a first charge storage component having a first terminal connected to said charging circuit and a second terminal connected to a power supply common voltage;
a secondary charging circuit connected to said first terminal of said first charge storage component;
a second charge storage component having a first terminal connected to said secondary charging circuit and a second terminal connected to said power supply common voltage; and
a converter having an input terminal and an output terminal, said input terminal receiving an input voltage from said first terminal of said second charge storage component, and said output terminal supplying an output voltage with a magnitude altered relative to said input voltage.

Abstract
A power distribution network includes multiple charge storage components and multiple charging circuits to control the charging and discharging of the charge storage components, which may comprise a battery and a supercapacitor. By appropriate arrangement and selection of the storage components, ripple in the power supply voltage, whose propagation to other components relying on the power distribution network may cause an audible buzz, may be significantly reduced. Additionally, appropriate arrangement and selection of the storage components, electromagnetic interference may also be significantly reduced.
