Implementation of Various Modulation Techniques to a PV Fed Solar Inverter with High Gain DC-DC Converter in Standalone Applications

The installed capacity of solar power producing systems has expanded during the past several decades. As a result of varying weather conditions, the output of a PV array is often an unregulated DC supply. Using a high step-up DC-DC converter, the maximum power is monitored in response to temperature and irradiance. This converter can increase more voltage than a traditional boost converter, and as a result, the switch is subjected to little stress. The incremental conductance approach achieves maximum power point tracking (MPPT). The incremental conductance technique enhances efficiency and can follow any parameter change. The output of high step-up DC-DC converter is the input to the inverter. Various pulse width modulation methods are used to a diode-clamped multilevel inverter in this study. MATLAB is used throughout the whole process of designing and developing the system. The outcomes of the simulation show that the MPPT algorithm may operate well with a number of different Pulse Width Modulation strategies when applied to a five-level diode clamped multi-level inverter in stand alone system.
