Recently the growth of DC operative home appliances like mobile and lap top chargers, ovens and hair dryer's etc. are increasing and therefore a DC/DC converter is an efficient way to meet the electricity need from the local DER and helps in improving the system efficiency. This paper presents simulation results of a buck boost converter, MPPT algorithm (P & O method) for solar PV module and closed loop PI control system for obtaining constant 12 V and 24 V DC output voltage at DC bus. The proposed methodology is to extract maximum DC power from solar PV system and it is directly fed to DC load or DC Nano grid.en-USfalseDistributed energy resources (DERs) | Maximum power point tracking (MPPT) and Perturb & observe (PandO)Conference Paper19 January 201613738706511
