Fuzzy based MPPT System for Driving BLDC Motor

摘要

Now a days one of the economical source of energy is photovoltaic energy since it is free and plentiful in most part of the world. Photovoltaic system converts solar energy into electrical energy. Using FLC (Fuzzy Logic control) theory this paper presents a maximum power point tracking system for PV. The fuzzy controller produces a control signal for the pulse-width-modulation which in turn regulate the duty ratio of the boost converter to match the load impedance and maximizes the motor speed. During night and bad weather condition PV is not available. To ensures the continuity of supply to load stand alone PV system is used here. This paper presents a stand alone PV system with BLDC motor as load.
