本文研究了用于逆变器PWM控制的增量调制器的动力学特性。首先,我们介绍了范式电路方程和一维返回图。然后我们阐明了系统在宽参数区域表现出非周期行为。其次,我们在电路中应用强制开关。这种开关可以使控制逆变器的宽参数区域内的运行稳定,而在其他参数区域则会引起混沌现象。
This paper studies dynamics of the delta modulators for PWM control of inverters. First, we introduce normal form circuit equation and 1-D return map. We then clarify that the system exhibits nonperiodic behavior in wide parameter region. Second, we apply compulsory switching to the circuit. This switching can stabilize the operation in some wide parameter region for controlling inverters and can cause chaotic phenomena in other parameter region.
