多电平变流器技术受到了越来越多的关注，尤其是在大功率应用中。特别是，三级驱动系统已被广泛报道。本文研究了一种用于驱动的四电平整流-逆变系统。描述了一种动态控制算法，该算法主要从整流器处平衡四电平整流-逆变器驱动系统的电压。所提出的控制方法还可以在电力系统接口处产生单位功率因数电流。逆变器调制相对不受约束，并被修改以实现零序补偿以增加电压平衡。仿真结果验证了控制算法的有效性。
Multilevel converter technology has been receiving increased attention, especially for high power applications. In particular, three level drive systems have been extensively reported. In this paper, a four level rectifier-inverter system is investigated for drive applications. A dynamic control algorithm is described which balances the voltages on a 4 level rectifier-inverter drive system primarily from the rectifier. The proposed control method can also generate unity power factor currents at the utility interface. The inverter modulation is relatively unconstrained and modified to implement a zero sequence compensation for added voltage balancing. Simulation results are used to verify the efficacy of the control algorithm.
