Abstract

Abstract A power control system having a range power control and a power distribution control circuit cascaded with the range power control. The power distribution control circuit distributes power from the range power control to a plurality of loads equal to a predetermined value. The range power control comprises a full wave bridge rectifier having a pair of fixed diodes and pair of silicon controlled rectifiers. The bridge circuit provides phase controlled full wave rectified power output. The power distribution control includes an independent section and a dependent section, each section having a load. Changes in power output of the independent section load in turn varies the power output of the dependent section load resulting in a constant power distribution between the loads. A delay network is used to couple the independent section to the dependent section.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 91 words
A power control system comprising: a range power control means; and a power distribution control circuit cascaded with said range power control means for distributing power which is equal to a predetermined value from said range power control means through a plurality of loads said power distribution control circuit comprising an independent section and a dependent section, each having a load, and wherein changes in power output of said independent section load in turn varies the power output of said dependent section resulting in a constant power distribution between said loads.
Claim 2
Dependent Claim 91 words
A power control system comprising: a range power control means; and a power distribution control circuit cascaded with said range power control means for distributing power which is equal to a predetermined value from said range power control means through a plurality of loads said power distribution control circuit comprising an independent section and a dependent section, each having a load, and wherein changes in power output of said independent section load in turn varies the power output of said dependent section resulting in a constant power distribution between said loads.
Claim 3
Dependent Claim 39 words
A power control system in accordance with claim 1 wherein said power distribution control circuit independent section and dependent section are interconnected by means of a delay network for controlling the amount of power output of the dependent section.
Claim 4
Dependent Claim 22 words
A power control system in accordance with claim 2 wherein said delay network is formed of a differentiating circuit and integrating network.
