A modified multilevel inverter with a configurable level generation is proposed in this paper. The MLI is composed of a modified boost converter at the front end followed by a level generation circuit and a H-bridge configuration. The front-end converter is biased with a PV source with a Hybrid boost resonant converter. The switches are triggered out of phase through a MPP tracker which uses Fractional INC MPPT. The secondary side of the circuit is composed of a derived voltage doubler along with the voltage regulator. The output of the doubler is regulated through a level converter which integrates a fuzzy controller and a phase shift controller. The modified multilevel inverter uses a low-voltage PV source as input and generates a variable-step multilevel output voltage with lower harmonic distortion and it is suitable for low-power PV applications.
