Abstract

Purpose The conventional two-level inverter suffers from harmonics, higher direct current (DC) link voltage requirement, higher dv/dt and heating of the rotor. This study aims to overcome by using a multilevel inverter for brushless DC (BLDC) drive. Design/methodology/approach This paper presents a comparative analysis of the conventional two-level and three-level multilevel inverter for electric vehicle (EV) application using BLDC drive. Findings A three-level Active Neutral Point Clamped Multilevel inverter (ANPCMLI) is proposed in this paper which provides DC link voltage control. Simulation studies of the multilevel inverter and BLDC motor is carried out in MATLAB. Originality/value The ANPCMLI fed BLDC simulation results shows that there is the significant reduction in the BLDC motor torque ripple, switching stress and harmonic distortion in the BLDC motor fed ANPCMLI compared to the conventional two-level inverter. A prototype of ANPCMLI fed BLDC drive along with field programmable gate array (FPGA) control is built and MATLAB simulation results are verified experimentally.

采用无刷直流电机驱动的电动汽车用二电平和三电平多电平逆变器的对比分析

目的传统的二电平逆变器存在谐波、直流环节电压要求高、dv/dt高和转子发热等问题。本研究旨在通过使用多电平逆变器进行无刷直流（BLDC）驱动来克服这一问题。设计/方法/方法本文对使用无刷直流驱动的电动汽车（EV）应用中的传统两电平和三电平多电平逆变器进行了比较分析。本文提出了一种三电平有源中性点箝位多电平逆变器（ANPCMLI），用于直流环节电压控制。在MATLAB中对多电平逆变器和无刷直流电机进行了仿真研究。原始值ANPCMLI馈给的无刷直流仿真结果表明，与传统的两电平逆变器相比，ANPCMLI馈给的BLDC电机的转矩脉动、开关应力和谐波失真显著降低。建立了ANPCMLI供电的无刷直流驱动器与现场可编程门阵列（FPGA）控制的原型，并对MATLAB仿真结果进行了实验验证。
