基于自举电路的逆变器系统准六步运行以提升转矩能力

This article proposes a control scheme for quasi-six-step operation with a voltage constraint to improve the torque capability of low-cost drives with bootstrap circuits. Voltage utilization is limited for a low-cost drive system embedded with a bootstrap circuit, where only the linear modulation is considered. To improve torque capability, overmodulation (OVM) can be achieved by shifting the volt...
