Power System with Power Converters Having an Adaptive Controller
First 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 and 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.

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.
