Abstract:
1. A power system for applying power to a load, comprising: a power generator configured to apply power to the load based upon a power set point that is indicative of a level of power to be applied to the load; a controller coupled to the power generator, the controller configured to control a rail voltage signal and a gate bias signal, where the controller controls both the rail voltage signal and the gate bias signal to maintain the power set point, and also improve operational performance of the power system in response to indicia of operational performance of the power system, and the controller increases the gate bias signal to maintain the power set point when the level of the power that is applied to the load drops below the power set point; and a performance assessor, coupled to the power generator and coupled to the controller, the performance assessor configured to provide the indicia of operational performance of the power system to the controller, where the indicia of the operational performance are relative to a plurality of metrics indicative of operational efficiency of the power system.
