Power Electronic devices plays an important role to control and convert electrical power from one form to another. The system which performs the power processing is called a converter. Converter can perform the function of rectifying (AC to DC), inverting (DC to AC), boosting (DC to DC), and frequency conversion (AC to AC). The device which is used to convert DC to AC is called inverter. Inverters are classified into two types, current source inverter (CSI) and voltage source inverter (VSI). The demerits of CSI and VSI can overcome by using the proposed concept. The proposed concept gives voltage boost and it provides short circuit protection. Two different methods are used to boost the output voltage, simple boost control method and fuzzy logic control method. The obtained output voltage of QZSI and total harmonic distortion (THD) are compared and analysed. The proposed concept is used for the applications of grid connected photovoltaic systems, electric vehicles and adjustable speed drives.
