Abstract

This paper introduces an optimal transient mitigation controller for boost-Type converters that is enabled by an accurate load estimation procedure. The controller incorporates a peak current programmed mode control for steady-state operation and a nonlinear, state-plane-based transient-mode control schemes for load transients. The load estimation procedure operates on present information alone, without the need for prior knowledge of the system parameters. The operation of the controller and the load estimation procedure is experimentally verified on a 2-15V to 3.3V non-inverting buck-boost converter, demonstrating accurate load estimations for various loading events thus enabling optimized recovery patterns to steady-state.
