N2 - This paper introduces a new transient-oriented controller for boost-type converters. The controller incorporates a peak current programmed mode control for steady-state operation and a non-linear, stateplane based transient-mode control for load transients. The new controller facilitate convergence from a loading transient to the new steady-state point within the minimum possible time while constraining the output voltage deviation to a desired (minimal) value. As a result, the loading transient performance of indirect energy transfer converters may be significantly improved since two control objectives (convergence time and undershoot) are simultaneously obtained. A detailed principle of operation of the controller is provided and explained through a stateplane analysis. The operation of the controller is experimentally verified on a 30W 3.3V-to-12V boost converter, demonstrating a significantly lower output voltage deviation and lower peak inductor current when compared to time-optimal control, allowing for volume reduction of the converter.
