Power system with power converters having an adaptive controller
DC CAFCFirst Claim
1. A power converter coupled to a power system controller configured to receive a signal indicating a system operational state of a load coupled thereto, comprising:
- a power switch configured to conduct for a duty cycle to provide a regulated output characteristic at an output thereof; and
a controller configured to receive a command from said power system controller to enter a power converter operational state as a function of said signal indicating said system operational state, said controller further configured to provide a signal to control said duty cycle of said power switch as a function of said output characteristic and in accordance with said command, thereby regulating an internal operating characteristic of said power converter to improve an operating efficiency thereof as a function of said system operational state.

Abstract
A power system having a power converter with an adaptive controller. The power system is coupled to a load and includes a power system controller that receives a signal indicating a system operational state of the load and selects a power converter operational state as a function thereof. The power system also includes a power converter with a power switch that conducts for a duty cycle to provide a regulated output characteristic at an output thereof. The power converter also includes a controller that receives a command from the power system controller to enter the power converter operational state and provides a signal to control the duty cycle of the power switch as a function of the output characteristic and in accordance with the command, thereby regulating an internal operating characteristic of the power converter to improve an operating efficiency thereof as a function of the system operational state.

16. A method of operating a power system coupled to a load, comprising:
-
receiving a signal indicating a system operational state of said load; generating a power converter operational state as a function of said system operational state; inducing a power converter to enter said power converter operational state; and providing a signal to control a duty cycle of a power switch of said power converter as a function of an output characteristic thereof and in accordance with said power converter operational state, thereby regulating an internal operating characteristic of said power converter to improve an operating efficiency thereof as a function of said system operational state. - View Dependent Claims (17, 18, 19, 20)
