Interleaved converter based PV connected BLDC motor with MPPT controller

Abstract

This paper presents a brushless dc motor drive, which is utilized as the load of a photovoltaic system with a maximum power point tracking (MPPT) controller. To achieve a fast and stable response for the real power control, the intelligent controller consists of a Perturb and Observe (P&O) for maximum power point tracking (MPPT) where the output signal is used to control the interleaved boost converters to achieve the MPP. A brushless dc (BLDC) motor drive system that incorporates a motor controller with proportional integral (PI) speed control loop. MATLAB/Simulink is used to build the dynamic model and simulate the system.
