    No full text
    &lt;div&gt;This paper presents a state of the art on brushless &lt;/div&gt;&lt;div&gt;Permanent Magnet Alternative Current (PMAC) and &lt;/div&gt;&lt;div&gt;Permanent Magnet Direct Current (PMDC) motor drives. The &lt;/div&gt;&lt;div&gt;brushless PMAC and PMDC motor drives are the latest choices &lt;/div&gt;&lt;div&gt;of researchers due to their high efficiency, silent operation, &lt;/div&gt;&lt;div&gt;compact size, high reliability, and low maintenance &lt;/div&gt;&lt;div&gt;requirements. These motors are preferred for numerous &lt;/div&gt;&lt;div&gt;applications. An in-depth analysis of PMAC and PMDC motor &lt;/div&gt;&lt;div&gt;drives have been discussed. The Permanent Magnets (PMs)&lt;/div&gt;&lt;div&gt;motor drives can be classified into two categories, first is PMAC &lt;/div&gt;&lt;div&gt;motor drives, i.e. PMSM and the second one is PMDC motor&lt;/div&gt;&lt;div&gt;drives, i.e. BLDC motors. There has been a long &lt;/div&gt;&lt;div&gt;misunderstanding between the two ways of driving and &lt;/div&gt;&lt;div&gt;controlling a motor with no windings on the rotor but only &lt;/div&gt;&lt;div&gt;PMs. In this paper given a comprehensive analysis of both &lt;/div&gt;&lt;div&gt;motor drives. So, beginner of the research scholars are easily &lt;/div&gt;&lt;div&gt;able to understand about brushless PMAC and PMDC motor &lt;/div&gt;&lt;div&gt;drives.&lt;/div&gt;</jats:p

    Simulation of DC/DC converter for DC nano-grid integrated with solar PV generation

    Distributed energy resources (DER) based micro grid and Nano-grid framework is most technically viable bottom-top approach to sustainably meet ever-increasing demand of rural and urban communities. 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.by Rajesh M. Pindoriya, Naran Pindoriya and S. Rajendra
