In recent years, inverters are used in wide applications to have efficient current during power losses. The battery of the inverter stores the voltage of the current and emits current during power losses. Nowadays, solar energy is preferred for storing the voltage sources of the battery. But due to many unfavorable conditions, the battery provides insufficient voltage for the inverter. To overcome the issue, we proposed A single-phase nine-level inverter is implemented which fed with a photovoltaic system. A pulse-width-modulated (PWM) regulation strategy is handled to generate the PWM signals for the inverter. Typically, Maximum Power Point Tracking (MPPT) is permitted in this multilevel inverter to extract extremely high power from the sun at daytime. An adaptive MPPT procedure is deployed with a standard trouble and sense way for the PV system. The proposed work with a reduced number of switches converts DC to AC which is capable of producing nine levels of output-voltage levels from the dc supply voltage. The Pulse Width Modulation (PWM) signals are generated to the inverter by using PID and Fuzzy Controllers, and the total harmonic distortion (THD) results are compared. The voltage control of Single-Phase Induction Motor for better performance is discussed and implemented in MATLAB / SIMULINK. The Simulation circuit is analyzed, and results are discussed for the proposed method which has better accuracy in contrast with the traditional methods.
