Fuzzy Logic Controller for MPPT SEPIC converter and PV single-phase inverter
This paper introduces an implementation of Fuzzy Logic Controller (FLC) for the single-ended primary-inductor converter (SEPIC) that control the maximum power point tracking (MPPT) signal together with the cascaded single-phase inverter. The extracting of the maximum power through using the SEPIC fuzzy controller is considered the main improvement here. Fuzzy-controlling in duty cycle increases/decreases the voltage level for the SEPIC according to the maximum power. SEPIC MPPT ensures optimal utilization for the PV array. The controller further proves its accuracy in variable-load conditions. TMS320F28335 DSP has been used to implement the controlled pulse width modulation (PWM). The controlled system has been verified by simulation and implemented in a prototype. Then, experimental results have been compared with those for conventional single-phase inverter.
