说明：  在传统矩阵变换器和多电平逆变器的基础上,提出一种新颖的多电平矩阵变换器,介绍了其拓扑结构和工 作原理.多电平矩阵变换器的能量传递,是通过三相输入电压对中点电容充电到一个恒定直流电压而实现的.选择适 当的控制算法和电容电压,能在变换器的两侧合成低次谐波含量小且波形近似于正弦的可控输入/输出电压.对多电 平矩阵变换器进行建模和仿真,并探讨了其输出能控性. ( On the basis of a conventional matrix converter and a multilevel inverter, a novel multilevel matrix converter is proposed, and its topology configuration and principle are introduced. This converter operates as a bidirectional converter and transfers energy between its two sides by charging the midpoint capacitors to a known constant DC voltage level. Proper selection of control algorithms and capacitor voltages helps synthesize controllable and waveforms almost sinusoidal three-phases AC voltage with minimum low-order harmonics at both sides of the converter. The multilevel matrix converter is modeled and simulated with its output controllability discussed. )

本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)
