Comparative Performance Analysis of Isolated and Non-Isolated DC-DC Converters with Solar PV Array for EVs Application
Modern day’s power electronics converters are very important for each and every electronic device such as portable devices, cell phones, laptop-computers, electric vehicles, etc. For the Electric Vehicles (EVs) the dc-to-dc converters are the best-suited and essential devices on account of their lightweight, high efficiency, smaller size, and high-power density, bi-directionality, reliability, cost-effectiveness. This paper provides a comparative study on non-isolated and isolated power dc-to-dc converters for EVs in which the main power source is PV (photo-voltaic) array module, in addition, a brief idea about design and calculation of passive components of power dc-to-dc isolated and non-isolated converters both in theoretically, and practically with simulation software. Here all the simulation results are tested by MATLAB simulation software and verified that the multi-phase multi-device interleaved boost dc-dc converter (MDIBC) is the best-suited candidate for both low and high power photo-voltaic based EVs due to their compact size, low cost, reliability, multifunctionality, bi-directionality, high efficiency, etc.
