Abstract

This paper proposes a new control strategy for active power decoupling(APD) function of a bridge-less single-ended primary inductance converter(SEPIC). Without additional components, a change of control method would enable the implementation of APD functions, replacing an electrolytic capacitor(E-Cap) with a small film capacitor. The contribution of this paper is to apply a Lyapunov-function based control method to the control system to ensure global stability and reduce the number of sensors and parameters required for control. The effectiveness of the proposed control method is shown by simulations using MATLAB/SIMULINK.
