Abstract
A method (300, 400), device (100, 200), phone (200) and base station (200) provide an efficient tracking power converter for variable signals. The tracking power converter includes a feedforward feedback control unit that is coupled to receive a reference signal and to receive at least one feedback signal and is used for determining an optimal control signal in accordance with a predetermined scheme, a pulse width modulation unit that is coupled to the feedforward feedback control unit and is used for modifying a duty ratio to provide a switching signal, and a power converter that is coupled to the pulse width modulation unit and to a power source and is used for providing the dynamic variable output signal.
