High-efficiency MPPT Using ZVS quasi-resonant converter and PSO algorithm: Simulation and PIL validation

This paper presents the use of quasi-resonant converters for maximizing power extraction in residential photovoltaic (PV) applications, ensuring high efficiency and optimal energy quality. Quasi-resonant boost converters are implemented to optimize the power transfer process while minimizing switching losses and improving the overall performance of the system. The Particle Swarm Optimization (PSO) technique, which offers a reliable and flexible control mechanism for changing environmental conditions, is used to achieve Maximum Power Point Tracking (MPPT). The proposed system is modeled and simulated in MATLAB Simulink to validate its performance under different operating scenarios. Furthermore, real-time validation is conducted using the Processor-in-the-Loop (PIL) approach, implemented via the LAUNCHXL-F28379D microcontroller. The simulation and PIL results demonstrate the system’s capability to efficiently extract maximum power with high accuracy and energy quality, making it suitable for residential PV installations.
