Abstract :
This paper investigates the physical issues affecting the load transient response both from the power-stage-component-selection and control-design point of views. A conventional buck converter under three different control schemes - direct-duty-ratio control, peak-current control and peak-current-control with load-current-feedforward control - is used as an example. The outcomes of the investigation are validated by simulations and experimental tests.
