Modulation Control of Impedance Inverter to achieve Simple and Maximum Boosted Output

Abstract

India has seen a notable increase in adoption of the renewable energy, Various policies and schemes had been proposed in India to focalize on renewable energy sector. For solar energy conversion, an AC module that functions as a grid-connected inverter after a PV module is needed. ZSI is being used to alleviate a myriad of issues that VSI and CSI have. An impedance source inverter provided with triggering pulses generated by maximum boost control modulation technique is presented in this paper. The shoot-through control approach that is utilized to generate pulses that are sent to semiconductor switches is directly related to the output voltage of the ZSI. Among the several techniques that can be used, the one that involves the least amount of complexity is the one that is used here. The output of PV module which is mostly of lower range must be increased in able to link to the grid due to its inconsistent and fluctuating nature. This study compares and contrasts the modulation techniques used for 3-ZSI in order to highlight their fundamental differences. It then offers a practical method for obtaining high output voltage with minimal voltage stress on the inverter's switching components.
