For conventional boost converters, switching stress will be more at high gain, in order to alleviate this problem three level boost converters are used. The mismatched voltage levels between the dynamic lower voltage and the required constant higher voltage of the DC link bus of the inverter can be solved using flying-capacitor based three-level boost converter with a quasi-Z source (TLBqZ). The operating principle of wide range voltage-gain for this topology is according to the effective switching states of the converter and the multi-loop energy communication characteristic of the quasi-Z source. The dynamic self-balance principle of the flying capacitor voltage is utilized. An analysis is done on the performance of the converter with PI and fuzzy controller. The fuzzy logic controller is used for switching pulse generation in the converter, as it is more advantageous over PI controller. An H-bridge inverter is fed from the converter that connects to the AC loads. The simulation of the circuit is performed in MATLABR2014a and waveforms are analyzed. An experimental prototype of the converter is implemented using dsPIC30F2010 microcontroller and results are verified.
