This paper focuses on the development of open and closed loop system for nine level cascaded H-Bridge multilevel inverter (CHBMLI). Inverters are often used to provide power to electronics in case of a power outage where no power is available. An inverter converts a DC voltage into an AC voltage. But main drawbacks of these inverters are high harmonic content and limited power applications. This is the main problem identified in conventional system. In order to overcome this problem, a new topology of CHBMLI is presented, which increases the level number of output waveform and thereby reduces the low-order harmonics and THD. The proposed system consists of a PV module, DC-DC converter with capacitor filter and DC-AC multilevel inverter. In this paper, an equal pulse width modulation (E-PWM) technique, applicable for proposed CHBMLI is presented. The proposed nine level cascaded H-bridge multilevel inverter achieves higher power ratings, and also enables the use of renewable energy sources in an efficient manner. Simulation results are compared with theoretical results.Index terms- cascaded H-bridge multilevel inverter (CHBMLI); Equal pulse width modulation (EPWM); Total harmonic distortion (THD); Photovoltaic (PV); Separate DC sources (SDCS).
