摘要
提出一种新的随机空间矢量PWM调制策略,通过FSM形成空间矢量PWM过程,实现有限状态之间的随机转换,从而对电压空间矢量进行随机调制.将此策略由两电平推广到三电平,发展了基于此策略的多电平随机空间矢量PWM方法.这种随机调制策略易与提高开关频率相结合,适合于数字实现.仿真和实验结果证明这种随机空间矢量PWM策略有效可行.
A novel randomized space vector PWM scheme with FSM approach is proposed in this paper. Random modulation for the voltage space vector compatible with the switching frequency variation is achieved by randomly transforming between finite states. Furthermore, the strategy, which suits digital application, is applied to an extension of three - level. As a result, multi - level randomized space vector PWM method based on FSM approach is developed. Simulations and experimental results confirm the validity of it.
