通过微小的电容量的变化来感知位移变化的大小，以此来进行信号的处理和输出，电路分：正弦波激励信号产生部分、传感器电桥部分、信号放大部分，放大器整流部分及放大器进行滤波部分组成，能稳定运行及仿真成功。

为了实现这个目标，我开始分别实现低通和高通滤波器，最后添加了一个放大器来放大我的信号。 因此，通过将高通和低通滤波器级联在一起，我获得了带通滤波器。 带通滤波器的范围 = [fc1 , fc2]。 fc1：高通滤波器的截止频率。 fc2：低通滤波器的截止频率。 fc1 = 1/(2*pi*R1*C1) fc2 = 1/(2*pi*R2*C2) 放大 := 1+(R4/R3)

针对中压应用场合，提出一种新型的n+1混合式模块化多电平换流器(HMMC)拓扑结构。在传统单桥臂n个子模块的模块化多电平换流器(MMC)基础上，加入1个全桥子模块，使其电容电压控制为半桥子模块的一半，实现输出电压电平数由原先的n +1增长至2n+3。针对其结构提出一种混合式调制方式，在保证HMMC稳定工作的基础上，降低HMMC子模块的工作开关损耗。由于全桥、半桥子模块电容电压不一致，采用一种电容预充电方式，并对子模块电容电压建立数学模型，提出一种子模块电容电压平衡的控制策略。在MATLAB/Simulink软件中搭建仿真模型，仿真结果验证了所提拓扑结构和控制策略的有效性和正确性。
