This paper describes the design of rule based fuzzy logic controller (FLC) for the multilevel inverter connected to the solar panel. In general the multilevel inverters are effective means of reducing harmonic distortion and provide low electromagnetic interference (EMI) and low change in voltage at the output voltage. The PWM based on space vectors (SVPWM) technique is used in this multilevel inverter. The SVM enables balancing the voltages of dc capacitors and provides switching at low frequency thus reducing the switching losses of the inverter. This scheme leads to be able to control the output voltage of the five level diode clamped inverter by using the fuzzy logic controller. The proposal is verified in simulation to evaluate the validity of the inverter in MATLAB.
