DESIGN AND ANALYSIS OF PV SYSTEM WITH Z-SOURCE HALF-BRIDGE CONVERTER
ABDUL SHAHID ANSARI,  Er. DHARMENDRA SINGH
In a grid-connected photovoltaic (PV) system, the traditional Z-source inverter uses a low frequency transformer to ensure galvanic isolation between the grid and the PV system. Half bridge converter system is developed for to convert dc power in to the ac and also boost dc output. Due to less no of switches, complicity of converter has been reduced. By adding this Z-source network in between the half bridge converter then this half bridge converter can be also able to operate if duty ratio goes beyond the unity. Conventional half bridge Z-source converter can be used for resistive load. By using the simulation results we can analyze the proposed method. This paper presents a modified single-phase transformerless Z-source PV grid-connected inverter and a corresponding PWM strategy to eliminate the ground leakage current in order to combine the advantages of both Z-source inverters and transformerless PV inverters.
Keywords- Half-bridge converter, reduced number, shoot-through, Z-source
