Integrated SPV-Battery BLDC Motor Drive Powered By Interleaved Boost Converter

Abstract

Brushless Direct Current (BLDC) motors are one of the most rapidly expanding motor types. The modelling and control of a solar-powered BLDC motor drive are discussed in this paper. Solar photovoltaic (SPV) panels are linked to the three-phase Voltage Source Inverter (VSI) that uses a DC-DC Interleaved Boost converter (IBC) to power the BLDC motor. When operating under different dynamic conditions, Maximum Power Point Tracking (MPPT) control algorithms can enhance the effectiveness of photovoltaic (PV) plants. PV systems have variable outputs that change with temperature and irradiance levels. When using a traditional boost converter, we experience a significant voltage ripple. When compared to a typical boost converter, the power electronics converter IBC aids in reducing ripple in power, input current, and output voltage. The analysis and design of two-stage IBCs are presented in this paper. Because of its great efficiency and dependability, enhanced performance, and low cost, BLDC motors are the ideal choice. The system under consideration, as well as the control mechanism, are formulated and simulated in the MATLAB-Simulink. With inclusion of battery through bidirectional DC-DC converter, a constant and uninterrupted power supply is maintained despite shifting loads and irradiances. The battery’s charging and discharging modes are also considered in this chapter.
