Lyapunov based stability analysis of current self-control approach for single-phase PFC Boost converters subject to load variations

Abstract

The paper proposes a Lyapunov based approach for assessing the local stability of current self-control strategies for PFC Boost converters subject to load variations. Lyapunov stability conditions are cast in terms of state-dependent linear matrix inequality constraints which are numerically solved via semi-definite solver packages. Numerical simulations and practical experiments are considered to validate the proposed approach.
