There are keyboard and liquid crystal to demonstrate window on the frequency converter's control of face, but it can only realize manual operation, for realize the automatic control so we introduce SCM technology, as the result, between MCU and the frequency changer data communication can enhance the control ability and area of the frequency changer.

随着变频调速技术的发展，变频器调速已成为交流调速的主流，在化纤、纺织、钢铁、机械、造纸等行业得到广泛的应用。变频器控制面板上配有键盘及液晶显示窗口，但只能实现手工操作，为了进行自动化控制，因此引进单片机技术，实现单片机与变频器之间的数据通信，提高变频器的控制能力和控制范围。

This is my ISP programming experiment in the preparation of an independent structural description of the four full-adder, through the four mapping of a full adder means four full-adder function, together with a digital display module will be full adder computing the results output to a digital display.

详细说明：这是我在ISP编程实验中独立编写的采用结构化描述的四位全加器，通过四次映射一位全加器的方式实现了四位全加器的功能，并附有数码显示模块，将全加器的运算结果输出到数码管显示。

As an example, in the design of a 4-bit ripple carry adder, the second and fourth full adders do not use output inverters for carry generation. one inverter delay is eliminated for every two full adders in the adder chain, and four transistors are reduced. Similarly, in complex designs like the multiplier, the output inverters for generating sum and carry can be used in alternative stages, thereby improving speed and reducing area.

例如，在4位行波进位加法器中，第2级和第4级的加法器不需要用输出反向器进行进位产生，因此，加法器链上的反向器延迟每两级全加器抵消一次，因此可以减少4个晶体管，类似的，在乘法器这样的复杂设计中，用于产生"和"以及"进位"的输出反向器可以用于其它方面，因此可以改善电路的速度和减小面积。

根据辅助电源高可靠性、高稳定性、低电磁干扰、良好的高频隔离的要求，通过对不同拓扑类型的分析比较，选择半桥LLC谐振变换器作为前级变换器，交流母线和零式全波整流结构作为后级变换器，在母线和后级变换器的连接上采用1∶1的隔离变压器连接。
