基于二极管辅助Buck-Boost逆变器的无刷直流电机换相转矩脉动抑制策略

Based on diode-assisted buck–boost inverter, this paper proposes a new commutation torque ripple suppression strategy for brushless dc motor (BLDCM). Four types of switching vectors are constructed, according to the working pattern of the diode-assisted inverter and the operation mode of the BLDCM. Moreover, the effects of switching vector combination on commutation torque ripple suppression and m...
