跟踪带宽高是快速参考跟踪电源的一项重要性能。基于多电平开关变换串联线性调节的混合拓扑方案,并在分析直接参考跟踪控制方法优缺点的基础上,提出了间接参考跟踪控制方法。该方法一方面将给定参考信号进行包络提取,并将该包络作为多电平开关变换的控制参考;另一方面将给定信号进行延时处理,延时后的信号作为后级线性调节的控制参考。间接参考跟踪控制方法下,多电平开关变换的开关频率等于给定参考信号的包络带宽,与直接参考跟踪控制方法
Tracking bandwidth is a fast reference tracking power of an important performance. Based on the hybrid topological scheme of multi-level switch transform series linearity regulation, and based on the analysis of the advantages and disadvantages of the direct reference tracking control method, an indirect reference tracking control method is proposed. On the one hand, this method extracts the envelope of a given reference signal and uses the envelope as a control reference for the multi-level switch transform. On the other hand, the given signal is delayed, and the delayed signal is used as the latter linearity Adjustment control reference. Under the indirect reference tracking control method, the switching frequency of the multi-level switch is equal to the envelope bandwidth of a given reference signal, and the direct reference tracking control method
