Abstract

Multi-port power converters have gained attention in renewable energy applications due to their higher power density caused by fewer number of components. Three-port converters (TPCs) provide desirable solution to many applications combining renewable energy sources (RESs) and energy storage systems (ESSs). This paper proposes a new TPC with an adaptive variable-frequency PWM (VF-PWM) control scheme to assure its operation in boundary current mode (BCM). The proposed TPC provides a feasible solution to combine a PV with a battery system for residential PV systems. This paper discusses the proposed TPC and its operation modes. Moreover, the suggested VF-PWM method is introduced to achieve BCM of the proposed TPC. The provided simulation results verify the effectiveness and feasibility of the proposed TPC and its VF-PWM method for BCM operation. Quantitative discussions on benefits of BCM from various aspects are also presented.
