Design of Solar-PV Operated Formal DC-DC Converter Fed PMBLDC Motor Drive For Real-time Applications

Abstract

In this work, the performance of BLDC motor is evaluated by considering two different applications which are so realistic to real time systems such as Electric-Vehicle Transportation system and water-pumping system based irrigation applications. In general, BLDC motor is powered by either DC source or Renewable Energy Sources (RS) with a power-electronic inverter followed by high voltage-gain boost DC-DC converter. In this work, SPV system is considered and interfaced to two real-time applications with the help of power-conditioning systems, it consists of high-voltage gain DC-DC converter and DC-AC inverter with attractive control schemes. The evolution of DC-DC converters with greater voltage gain converter is required, it transforms low-level SPV voltage to high-level DC-bus voltage with attractive Maximum-Power Point-Tracker(MPPT) algorithm is placed to attain the pre-requisite efficiency. Unfortunately, formal DC-DC converters are not preferable because of extreme duty ratios. So as to implement a high voltage gain DC-DC converter, several types of converters are reviewed. A conventional DC-DC boost converter is selected for driving the PM-BLDC drive powered by Solar-PV system. The performance of PM-BLDC motor is evaluated under fixed speed and variable speed conditions by using Matlab/Simulink tool, results are presented.
