Low Current Ripple Control Using Particle Swarm Algorithm Based Modified Boost Converter for MPPT Application

Low current ripple in the boost converter is crucial in renewable energy system design due to its potential impacts on the operation of other devices. One device that can be directly affected is the MPPT controller. To address this issue, a modified boost converter has been introduced to yield a lower current ripple compared to that of the standard boost converter. This paper presents a study conducted on the modified boost converter when connected to a PV array and a switch controlled by MPPT utilizing Perturb & Observe (P&O) and Particle Swarm Optimization (PSO) algorithms. The simulation results show that the PSO algorithm is more reliable than the P&O algorithm under various irradiation conditions. PSO can minimize steady-state oscillation and the capability to track maximum power than P&O.
