A Novel L-Z Source Inverter with Improving of Classical Z Source Inverter

Dubasi Nirosha

Abstract: On the basis of the classical ZSI (Z source inverter) provides a common ground for the DC source and Inverter, and avoids the disadvantages caused by capacitor in the Classical ZSI and SL-ZSI, especially in prohibiting the inrush current at startup. The inverter uses a unique inductor and diode network for boosting its output voltage. This inverter can improve the boost factor through adjusting shoot-through duty ratio and increasing the number of inductors. This thesis presents a novel ZSI uses a unique inductor and diode network with reducing inrush current. The working principle experimental results are analyzed in detail.
