When a PV module is required, an AC module that serves as a grid-connected inverter can be used. ZSI is being utilized to relieve VSI and CSI of a variety of problems. The use of renewable energy has increased noticeably in India, where a number of laws and programs have been proposed to focus on the renewable energy sector. Conventional voltage source inverters (VSIs) and current source inverters (CSIs) can only convert dc to ac via boost or buck methods. Consequently, VSI needs to install an extra DC-DC boost converter between the inverter bridge and the DC supply in order to get a higher AC output voltage..The triggering pulses are generated by bringing the input sinusoidal and triangular waves on the same graph. Maximum boosted output and constantly boosted can be achieved through this method just by adjusting its modulation index and shoot-through intervals. This work presents an impedance source inverter that is equipped with triggering pulses produced by maximum constant boost control modulation and maximum voltage boosting approach.
