Abstract:
1. A pulse width modulation power supply system comprising: a pulse width modulated power supply configured to provide power to a load, wherein the load is configured to operate in at least a first discrete power state and a second discrete power state; wherein the pulse width modulated power supply includes a controller configured to control an output of the pulse width modulated power supply in accordance with a predetermined state transition drive function during a power state transition of the load between the first discrete power state and the second discrete power state thereby providing a maximally flat voltage response in the load during a current transient of the power state transition, wherein the predetermined state transition drive function is based on a predefined model of a circuit including the pulse width modulated power supply system and the load, and wherein the predefined model of the circuit includes at least analogous elements of inductance, capacitance, load, and power switching characteristics.
