Abstract

Quasi-Z-source inverter (qZSI) is a new topology attractive in comparison to two-stage models due to their compactness, low cost, and reliability [15]. However, the derived from the traditional Z-source inverter (ZSI). The paper proposes an artificial-intelligence-based solution to interface and deliver maximum power from a photo- conventional inverter has to be oversized to cope with the wide PV array voltage changes because a PV panel presents low output voltage with a wide range of variation based on voltaic (PV) power generating system.The interface irradiation and temperature, usually at a range of 1 : 2. To between the PV dc source and the load is accomplished by a quasi-Z-source inverter (qZSI). The maximum power delivery to the load is ensured by an adaptive neuro fuzzy inference system (ANFIS) based on maximum power point tracking (MPPT). The proposed ANFIS-based MPPT offers an extremely fast dynamic response with high accuracy. The closed-loop control of the qZSI regulates the shoot through duty ratio and the modulation index to effectively interface the low voltage output of an inverter to the grid, a bulky low-frequency transformer is necessary at the cost of a large size, decrease in efficiency, loud acoustic noise, and high cost. The two-stage inverter applies a boost dc/dc converter instead of a transformer in order to minimize the required KVA rating of the inverter and boost the wide range of voltage to a constant desired value. Unfortunately, the control the injected power and maintain the stringent voltage, current, and frequency conditions.
