Power system with power converters having an adaptive controller

A power system coupled to a load, comprising:

• a power system controller configured to receive a signal indicating a system operational state of said load and to select a power converter operational state selected from the group consisting of a fully operational state, a reduced redundancy operational state and an idle operational state as a function thereof;
• and
• a power converter, including:
• 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 said power converter 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.

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 selected from the group consisting of a fully operational state, a reduced redundancy operational state and an idle 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.
